  • Missing time zones in OSX and Windows

    - by pellepim
    I am working on a javascript to automatically detect a user's timezone (https://bitbucket.org/pellepim/jstimezonedetect/). But there are two timezones that I have a really hard time to test, since I can not set my system to observe these timezones. The timezones I am talking about are UTC+1245 (Chatham Islands, NZ) and UTC+0845 (Australia/Eucla). As far as I can tell in OSX (Snow Leopard) and in Windows 7 these timezones do not exist as a setting. Granted, very few people live in these areas, and it might just not be worth it. Does anyone know of a way to set these timezones on a system level? In any operating system? If it is not possible in a trivial way, what do people who live in these areas do to get their systems working as they would like?

  • Optimizing python code performance when importing zipped csv to a mongo collection

    - by mark
    I need to import a zipped csv into a mongo collection, but there is a catch - every record contains a timestamp in Pacific Time, which must be converted to the local time corresponding to the (longitude,latitude) pair found in the same record. The code looks like so: def read_csv_zip(path, timezones): with ZipFile(path) as z, z.open(z.namelist()[0]) as input: csv_rows = csv.reader(input) header = csv_rows.next() check,converters = get_aux_stuff(header) for csv_row in csv_rows: if check(csv_row): row = { converter[0]:converter[1](value) for converter, value in zip(converters, csv_row) if allow_field(converter) } ts = row['ts'] lng, lat = row['loc'] found_tz_entry = timezones.find_one(SON({'loc': {'$within': {'$box': [[lng-tz_lookup_radius, lat-tz_lookup_radius],[lng+tz_lookup_radius, lat+tz_lookup_radius]]}}})) if found_tz_entry: tz_name = found_tz_entry['tz'] local_ts = ts.astimezone(timezone(tz_name)).replace(tzinfo=None) row['tz'] = tz_name else: local_ts = (ts.astimezone(utc) + timedelta(hours = int(lng/15))).replace(tzinfo = None) row['local_ts'] = local_ts yield row def insert_documents(collection, source, batch_size): while True: items = list(itertools.islice(source, batch_size)) if len(items) == 0: break; try: collection.insert(items) except: for item in items: try: collection.insert(item) except Exception as exc: print("Failed to insert record {0} - {1}".format(item['_id'], exc)) def main(zip_path): with Connection() as connection: data = connection.mydb.data timezones = connection.timezones.data insert_documents(data, read_csv_zip(zip_path, timezones), 1000) The code proceeds as follows: Every record read from the csv is checked and converted to a dictionary, where some fields may be skipped, some titles be renamed (from those appearing in the csv header), some values may be converted (to datetime, to integers, to floats. etc ...) For each record read from the csv, a lookup is made into the timezones collection to map the record location to the respective time zone. If the mapping is successful - that timezone is used to convert the record timestamp (pacific time) to the respective local timestamp. If no mapping is found - a rough approximation is calculated. The timezones collection is appropriately indexed, of course - calling explain() confirms it. The process is slow. Naturally, having to query the timezones collection for every record kills the performance. I am looking for advises on how to improve it. Thanks. EDIT The timezones collection contains 8176040 records, each containing four values: > db.data.findOne() { "_id" : 3038814, "loc" : [ 1.48333, 42.5 ], "tz" : "Europe/Andorra" } EDIT2 OK, I have compiled a release build of http://toblerity.github.com/rtree/ and configured the rtree package. Then I have created an rtree dat/idx pair of files corresponding to my timezones collection. So, instead of calling collection.find_one I call index.intersection. Surprisingly, not only there is no improvement, but it works even more slowly now! May be rtree could be fine tuned to load the entire dat/idx pair into RAM (704M), but I do not know how to do it. Until then, it is not an alternative. In general, I think the solution should involve parallelization of the task.

  • Why is this giving me 2 different sets of timezones?

  • How can I switch timezones in Perl's Template::Plugin::Date?

    - by aidan
    I have a calendar on my website, generated in Perl using Template::Toolkit and Template::Plugin::Date. It highlights the current day. I achieve this by iterating through all the dates (as I print the calendar) and comparing against the current date. Something like this: [% IF cur_date == date.format(format = '%Y-%m-%d') %] ... [% END %] It all works well until someone in Australia looks at it. (They are in a different timezone to me and my server in the UK). What's the best way to get Template::Plugin::Date to use a different time zone? It accepts a 'locale' parameter, but AFAIK this is only used for formatting.

  • How do I use timezones with a datetime object in python?

    How do I properly represent a different timezone in my timezone? The below example only works because I know that EDT is one hour ahead of me, so I can uncomment the subtraction of myTimeZone() import datetime, re from datetime import tzinfo class myTimeZone(tzinfo): """docstring for myTimeZone""" def utfoffset(self, dt): return timedelta(hours=1) def myDateHandler(aDateString): """u'Sat, 6 Sep 2008 21:16:33 EDT'""" _my_date_pattern = re.compile(r'\w+\,\s+(\d+)\s+(\w+)\s+(\d+)\s+(\d+)\:(\d+)\:(\d+)') day, month, year, hour, minute, second = _my_date_pattern.search(aDateString).groups() month = [ 'JAN', 'FEB', 'MAR', 'APR', 'MAY', 'JUN', 'JUL', 'AUG', 'SEP', 'OCT', 'NOV', 'DEC' ].index(month.upper()) + 1 dt = datetime.datetime( int(year), int(month), int(day), int(hour), int(minute), int(second) ) # dt = dt - datetime.timedelta(hours=1) # dt = dt - dt.tzinfo.utfoffset(myTimeZone()) return (dt.year, dt.month, dt.day, dt.hour, dt.minute, dt.second, 0, 0, 0) def main(): print myDateHandler("Sat, 6 Sep 2008 21:16:33 EDT") if __name__ == '__main__': main()

  • Why does Rails screw up timezones when I am editing a resource?

    - by DJTripleThreat
    Steps to produce this: prompt>rails test_app prompt>cd test_app prompt>script/generate scaffold date_test my_date:datetime prompt>rake db:migrate now edit your app/views/date_tests/edit.html.erb: <h1>Editing date_test</h1> <% form_for(@date_test) do |f| %> <%= f.error_messages %> <p> RIGHT!<br/> <%= text_field_tag @date_test, f.object.my_date %> </p> <p> WRONG!<br /> <%= f.text_field :my_date %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> <%= link_to 'Show', @date_test %> | <%= link_to 'Back', date_tests_path %> now edit your config/environment.rb: #add this config.time_zone = 'Central Time (US & Canada)' This recreates the problem I am having in my actual app. The problem with my app is that I'm storing a date in a hidden field and rendering a "user friendly" version. Creating a resource works fine but as soon as I try to edit it the time changes (it adds the difference between my current time zone configuration and UTC). go to http://localhost:3000/date_tests/new and save the time then go to reedit it and you will have two different representations of the date/time one which will save incorrectly and the other that will.

    i use the following method to send email to list of users i want the (To) in each email to be for just the user only not all users i.e appears to the users that the email is sent to only him my guess is to loop on: message.addRecipients(Message.RecipientType.TO, address); then send the message right? , but this is a heavy process sending an email many times any ideas ? suppose that i have the timezone for each user and i want to send each user the message in his timzone, the same issue i guess setting sent date for each user in his timezone then sending the message, right ? the method is: try { Properties props = System.getProperties(); props.put("mail.smtp.host", "localhost"); // Get a mail session Session session = Session.getDefaultInstance(props, null); // Define a new mail message Message message = new MimeMessage(session); InternetAddress ia = new InternetAddress(); ia.setPersonal("MySite"); ia.setAddress(from); message.setFrom(ia); Address[] address = new Address[recievers.size()]; for (int i = 0; i < recievers.size(); i++) { address[i] = new InternetAddress(recievers.get(i)); } message.addRecipients(Message.RecipientType.TO, address); message.setSubject(subject); // Create a message part to represent the body text BodyPart messageBodyPart = new MimeBodyPart(); messageBodyPart.setContent(body, "text/html"); // use a MimeMultipart as we need to handle the file attachments Multipart multipart = new MimeMultipart(); // add the message body to the mime message multipart.addBodyPart(messageBodyPart); // Put all message parts in the message message.setContent(multipart); message.setSentDate(getCurrentDate()); // Send the message Transport.send(message); } catch (Exception ex) {}

  • How do I find difference between times in different timezones in Python?

    - by JasonA
    Hi All, I am trying to calculate difference(in seconds) between two date/times formatted as following: 2010-05-11 17:07:33 UTC 2010-05-11 17:07:33 EDT time1 = '2010-05-11 17:07:33 UTC' time2 = '2010-05-11 17:07:33 EDT' delta = time.mktime(time.strptime(time1,"%Y-%m-%d %H:%M:%S %Z"))-\ time.mktime(time.strptime(time2, "%Y-%m-%d %H:%M:%S %Z")) The problem I got is EDT is not recognized, the specific error is "ValueError: time data '2010-05-11 17:07:33 EDT' does not match format '%Y-%m-%d %H:%M:%S %Z'" Thanks,

  • Is it possible to create a timer in jscript that you can manually change without it being affected by timezones?

    - by Lixorp
    is it possible to create a timer where I can manually set the hours each day to a set number of hours but still remains accurate? For example; if I set the countdown for 5 hours at 2pm I want the timer to stop as soon as it hits 7pm. Also, when I set the timer for 5 hours I would like everyone in the world to see it countdown from 5 hours, no matter what the time is in their country. In the format: days hours minutes seconds. The reason I want to do this is for a streamer's website. He needs a flexible timer which can be manually changed and is the same worldwide for his viewers to know when he starts streaming. The current timer we're using at the moment; setInterval(function(){ var currentTime = new Date(); if(currentTime.getHours() > 19){ var countdownHours = (24 - currentTime.getHours()) + 19; }else if(currentTime.getHours() < 19){ var countdownHours = 19 - currentTime.getHours(); }else{ var countdownHours = 0; } var countdownMins = 59 - currentTime.getMinutes(); var countdownSecs = 60 - currentTime.getSeconds(); $('#countdown-days h1').text('0'); $('#countdown-hours h1').text(countdownHours); $('#countdown-minutes h1').text(countdownMins); $('#countdown-seconds h1').text(countdownSecs); }, 1000); As you can tell it isn't ideal for what we need it for since it counts down to 7pm in the timezone you're in. Any help/examples would be greatly appreciated, Thank you in advance, Lixorp.

  • Cannot run logwatch due to Date::Manip issue

    - by Quintin Par
    I tried to run logwatch at follows [root@machine cron.daily]# ./0logwatch ERROR: Date::Manip unable to determine TimeZone. Execute the following command in a shell prompt: perldoc Date::Manip The section titled TIMEZONES describes valid TimeZones and where they can be defined. My date is as follows root@machine cron.daily]# date Thu Aug 23 06:25:21 GMT 2012 Now based on details in various forums I tried to fix this by setting /etc/timezone to “+0800” but it didn’t work My /etc/localtime points to /usr/share/zoneinfo/GMT and is managed by puppet How do I go about fixing this? I still want all my machines to be in GMT timezone. EDIT: Sadly, Both the changes are not working: [root@machine cron.daily]# cat /etc/TIMEZONE UTC Quanta’s [root@machine cron.daily]# cat ~/.bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin export TZ=GMT export PATH [root@machine cron.daily]# source ~/.bash_profile [root@machine cron.daily]# ./0logwatch ERROR: Date::Manip unable to determine TimeZone.

  • Globalization for GetSystemTimeZones()

    - by user300992
    I want to get a list of timezones, so that i can populate the dropdown list. In .NET 3.5, we have TimeZoneInfo namespace, here is the code: ReadOnlyCollection<TimeZoneInfo> timeZones = TimeZoneInfo.GetSystemTimeZones(); foreach (TimeZoneInfo timeZone in timeZones) string name = timeZone.DisplayName However, "DisplayName" is in English. How can I pass the cultureInfo so that it can return other languages? I tried setting the Thread.CurrentCulture and CurrentUICulture, it didn't work. Am I missing something?

  • Rails time zones

    - by Bob
    I'm calling an external web service API that returns a timezone as listed in the Olson timezones database (e.g. "America/New_York"). However some of the values the API returned are "US/Pacific", "US/Eastern" and apparently don't match any of the Olson timezones in Rails 2.3.2. Can anyone shed some light on this? Thanks in advance for your help.

  • Autodetect timezone in Rails given UTC offset and DST

    - by Jose
    I basically want to autodetect a user's timezone using Rails. I can use this JS code at the user's browser (http://www.onlineaspect.com/2007/06/08/auto-detect-a-time-zone-with-javascript/) to send a form with the UTC offset and the fact that the time zone observes DST during summer or not, in the user's time zone. Once I have that info in the server, I want to select the matching time zone. In Rails, I can get a list of time zones with ActiveSupport::TimeZone.all. Also, I can filter zones by utf offset thanks to the utc_offset method. However, I don't know how to filter the timezones that do/don't observe DST. E.g. suppose a user lives in Amsterdam. Filtering by UTC offset will return Berlin, Belgrado, Madrid, etc timezones, as well as West Central Africa. All of them, but West Central Africa, would be appropriate timezones for a user in Amsterdam (as they provide the same time/date), but I need to filter West Central Africa, which does not perform DST in summer. How can I do this in Rails? Also, are any of my assumptions wrong?

  • Joda-Time: DateTime, DateMidnight and LocalDate usage

    - by fraido
    Joda-Time library includes different datetime classes DateTime - Immutable replacement for JDK Calendar DateMidnight - Immutable class representing a date where the time is forced to midnight LocalDateTime - Immutable class representing a local date and time (no time zone) I'm wondering how are you using these classes in your Layered Applications. I see advantages in having almost all the Interfaces using LocalDateTime (at the Service Layer at least) so that my Application doesn't have to manage Timezones and can safely assume Times always in UTC. My app could then use DateTime to manage Timezones at the very beginning of the Execution's Flow. I'm also wondering in which scenario can DateMidnight be useful.

  • I18n translation problem

    - by kshchepelin
    I'm about to translate all time zones to Russian and I've done such things: model: # lib/i18n_time_zone.rb class I18nTimeZone < ActiveSupport::TimeZone def self.all super.map { |z| create(z.name, z.utc_offset) } end def to_s translated_name = I18n.t(name, :scope => :timezones, :default => name) "(GMT#{formatted_offset}) #{translated_name}" end end view: <%= time_zone_select :user, :time_zone, nil, :model => I18nTimeZone %> locale file (/config/locales/ru.yml): ru: timezones: "Midway Island": "??????" "Samoa": "?????" .... But there are cases when original string includes some dots (".") Like "St. Petersburg" And I18n.t() tells me that translation is missing. How can I avoid it?

  • Ubuntu worldtime desktop clock widget?

    - by ubuntico
    I am aware that in Unity we can add world time by clicking on time bar. However, it's still a list of locations and sometimes it may be hard to quickly find the timezone of interest. Is there any tool which can put a multiple clock instances on the desktop representing each timezone of interest? Similar to the clock in Windows 7. To be more clear, I am not looking for a weather widget, but a simple clock widget so that I can track time in different timezones.

  • Exchange 2010 update timezone of all calendar items

    - by Andrew
    We are currently operating Exchange 2010 server with Outlook 2010 clients on a ship. We have just changed timezones for the first time in quite a while today. Is there any way to rebase all the calendars and/or update all the calendar items to the new timezone at the same time? I have looked at the following tools already. Microsoft Exchange Calendar Update Configuration Tool - http://www.microsoft.com/en-us/download/details.aspx?id=6266 (Doesn't support exchange 2010) Time Zone Data Update Tool for Microsoft Office Outlook - http://www.microsoft.com/en-us/download/details.aspx?id=17291 The Time Zone Data Update Tool for Microsoft Office Outlook does work for individual users, but has some serious downsides. Including each user needs to run it (approx 400 users), and also it only seems to work on the default account in Outlook 2010, a lot of our users have role accounts as well that we would need to run the tool on. The only way I can find to get this tool to run on the role accounts is to make the role account the default account in outlook, and that in itself is quiet an involved process especially if you have 2 or 3 role accounts. So is there a way to just change all calendar items on our Exchange server to a different timezone in one go? We are a little unique in terms of the whole organisation can change timezones over night, meeting rooms and all, but surely a product as advanced as Exchange 2010 allows us to do what we need.
