• Python: How to get a value of datetime.today() that is "timezone aware"?

  - by mindthief

  Hi, I am trying to subtract one date value from the value of datetime.today() to calculate how long ago something was. But it complains: TypeError: can't subtract offset-naive and offset-aware datetimes The value datetime.today() doesn't seem to be "timezone aware", while my other date value is. How do I get a value of datetime.today() that is timezone aware? Right now it's giving me the time in local time, which happens to be PST, i.e. UTC-8hrs. Worst case, is there a way I can manually enter a timezone value into the datetime object returned by datetime.today() and set it to UTC-8? Of course, the ideal solution would be for it to automatically know the timezone. Thanks!

• dist-update kernel failed?

  - by AlbertK

  I run: sudo apt-get update sudo apt-get dist-upgrade , and the linux kernel seemed to be updated to 3.2.0-31-generic successfully. However, after I rebooted, I typed: uname -a , it showed : Linux Albert-PC 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Does that means the kernel wasn't being updated? I didn't encounter any error or warning messages during the upgrade or dist-upgrade. Thanks for any help

• Sometimes keyboard & touchpad work... sometimes not

  - by Voyagerfan5761

  When I first ran Ubuntu from CD on this Dell Inspiron 2650, it worked for about ten to fifteen minutes, then it hung (I was probably trying to do too much at once from a Live CD). The next time, my mouse and keyboard didn't work. I rebooted three times and finally got them working. I then installed Ubuntu alongside Windows XP. After installing, selecting the OS in GRUB worked, but my touchpad and keyboard were again not working. I rebooted, and they worked. (I fortunately had a USB mouse with which to reboot.) Booting Ubuntu and then rebooting to enable my keyboard and touchpad has become a routine ever since. Often several reboots are required; at one point I had to reboot over a dozen times in a row before getting a session where everything worked properly. (My installation has been in place for about three days a week now.) I've looked around for a device manager equivalent to no avail. Sometimes the hardware is properly detected, and sometimes it's not. Once or twice I've had the keyboard detected properly but the touchpad not. Plugging in my wireless card also sometimes requires a plug, unplug, and plug again to get it working. So is there some solution? I'm without an Internet connection at home, and this "laptop" is really a wall wart on my desk, so suggestions for packages may take a while to test. Xorg logs I captured two three four sample Xorg logs: one from a startup where the devices worked; one from when they didn't; one from a session where Ubuntu thought my touchpad was a normal mouse; and one from a session where my keyboard worked but the touchpad didn't. See this gist. Updated 2010-12-15 01:50 UTC with Xorg.0.log.keyboardonly file illustrating the case where the keyboard worked but not the touchpad. Updated 2011-01-11 04:10 UTC with Xorg.0.log.touchpadregmouse to illustrate a case where the touchpad was detected as a regular mouse (no "Touchpad" tab in mouse prefs).

• How to force a clock update using ntp?

  - by ysap

  I am running Ubuntu on an ARM based embedded system that lacks a battery backed RTC. The wake-up time is somewhere during 1970. Thus, I use the NTP service to update the time to the current time. I added the following line to /etc/rc.local file: sudo ntpdate -s time.nist.gov However, after startup, it still takes a couple of minutes until the time is updated, during which period I cannot work effectively with tar and make. How can I force a clock update at any given time? UPDATE 1: The following (thanks to Eric and Stephan) works fine from command line, but fails to update the clock when put in /etc/rc.local: $ date ; sudo service ntp stop ; sudo ntpdate -s time.nist.gov ; sudo service ntp start ; date Thu Jan 1 00:00:58 UTC 1970 * Stopping NTP server ntpd [ OK ] * Starting NTP server [ OK ] Thu Feb 14 18:52:21 UTC 2013 What am I doing wrong? UPDATE 2: I tried following the few suggestions that came in response to the 1st update, but nothing seems to actually do the job as required. Here's what I tried: Replace the server to us.pool.ntp.org Use explicit paths to the programs Remove the ntp service altogether and leave just sudo ntpdate ... in rc.local Remove the sudo from the above command in rc.local Using the above, the machine still starts at 1970. However, when doing this from command line once logged in (via ssh), the clock gets updated as soon as I invoke ntpdate. Last thing I did was to remove that from rc.local and place a call to ntpdate in my .bashrc file. This does update the clock as expected, and I get the true current time once the command prompt is available. However, this means that if the machine is turned on and no user is logged in, then the time never gets updates. I can, of course, reinstall the ntp service so at least the clock is updated within a few minutes from startup, but then we're back at square 1. So, is there a reason why placing the ntpdate command in rc.local does not perform the required task, while doing so in .bashrc works fine?

• Windows CE 6.0 time setting in registry being overrided

  - by JaminSince83

  I have asked this question on stack overflow but its probably better suited here. So I have a Motorola MC3190 Mobile Barcode scanning device with Windows CE 6.0. Now I want to get the device to sync its date/time on boot up with our domain controller using a registry file that I have created. I have used this registry file below to get close to what I require. REG 1 REGEDIT4 [HKEY_LOCAL_MACHINE\Services\TIMESVC] "UserProcGroup"=dword:00000002 "Flags"=dword:00000010 "multicastperiod"=dword:36EE80 "threshold"=dword:5265C00 "recoveryrefresh"=dword:36EE80 "refresh"=dword:5265C00 "Context"=dword:0 "Autoupdate" = dword:1 "server" = "NAMEOFMYSERVER" "ServerRole" = dword:0 "Trustlocalclock" = dword:0 "Dll"="timesvc.dll" "Keep"=dword:1 "Prefix"="NTP" "Index"=dword:0 [HKEY_LOCAL_MACHINE\nls] "DefaultLCID" = dword:00000809 [HKEY_LOCAL_MACHINE\nls\overrides] "LCID" = dword:00000809 [HKEY_LOCAL_MACHINE\Time] @ = "UTC" "TimeZoneInformation"=hex:\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 [HKEY_LOCAL_MACHINE\Time Zones] @ = "UTC" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Clock] "AutoDST" = dword:00000000 Now it gets the correct date and shows the time zone correctly however the time is always 5 hours behind on Eastern Standard Time, which is really annoying. I have researched heavily into this and this question has been asked before here As you will see I have copied what it suggests but it doesnt work. Something is overiding the time which I dont understand enough about to resolve. I cannot find any other setting to get it to set the time correctly. Any help would be greatly appreciated.

• Cisco ASA5505 won't sync with NTP

  - by Martijn Heemels

  Today I noticed that the clock my Cisco ASA 5505 firewall was running about 15 minutes late, which surprised me since I've set up the NTP client. My two NTP servers 10.10.0.1 and 10.10.0.2 are virtualized Windows Server 2008 R2 domain controllers, and both have the correct time. As shown below, the ASA knows about the two servers, can ping them and seems to poll them periodically, so I suppose it can reach them both. The ASA claims its time source is NTP, however the clock is unsynchronized. Neither host is marked as synced. Result of the command: "ping 10.10.0.1" Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.10.0.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms Result of the command: "sh ntp ass" address ref clock st when poll reach delay offset disp ~10.10.0.1 .LOCL. 1 78 1024 377 0.5 643.69 17.0 ~10.10.0.2 10.10.0.1 2 190 1024 377 0.9 655.91 58.4 * master (synced), # master (unsynced), + selected, - candidate, ~ configured Result of the command: "sh ntp stat" Clock is unsynchronized, stratum 16, no reference clock nominal freq is 99.9984 Hz, actual freq is 99.9984 Hz, precision is 2**6 reference time is 00000000.00000000 (07:28:16.000 CEST Thu Feb 7 2036) clock offset is 0.0000 msec, root delay is 0.00 msec root dispersion is 0.00 msec, peer dispersion is 0.00 msec Result of the command: "sh clock detail" 10:33:23.769 CEDT Tue Jun 26 2012 Time source is NTP UTC time is: 08:33:23 UTC Tue Jun 26 2012 Summer time starts 02:00:00 CEST Sun Mar 25 2012 Summer time ends 03:00:00 CEDT Sun Oct 28 2012 I've tried the basic steps of manually setting the time and removing and adding the timeservers, to no avail. My ASA's ntp config is simply: ntp server 10.10.0.1 ntp server 10.10.0.2 Do I need to enable authentication to use a Windows NTP server? Any thoughts?

When I try to restart the machine, I'm getting an error that the memory allocation failed, although more than enough memory is free. server ~ # free total used free shared buffers cached Mem: 16176648 16025476 151172 0 285432 950300 -/+ buffers/cache: 14789744 1386904 Swap: 0 0 0 server ~ # virsh start zimbra error: Failed to start domain zimbra error: Unable to read from monitor: Connection reset by peer server ~ # tail -n 4 /var/log/libvirt/qemu/zimbra.log LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 3072 -smp 2,sockets=2,cores=1,threads=1 -name zimbra -uuid d05ddb7a-83c4-a77b-d8bc-a322648520cf -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/zimbra.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -drive file=/var/lib/libvirt/images/zimbra.img,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -netdev tap,fd=19,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:21:a9:ad,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -vnc 192.168.1.2:25 -k de -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 char device redirected to /dev/pts/2 Failed to allocate 3221225472 B: Cannot allocate memory 2012-07-06 08:42:56.076+0000: shutting down server ~ # uname -a Linux server 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux The system is a Ubuntu 12.04 server. The problem seems to occurs since the last restart, which was due to a number of package upgrades and a kernel upgrade. I tried booting with the previous kernel, the problem persists. I was not able to pinpoint an exact event when the machines fail, they do it at nearly the same time. The last time a duplicity job was running, this was not always the case however. Any suggestions on how to debug this? Best regards, elm
