Node.js Cron Job Messing with Date Object
- by PazoozaTest Pazman
I'm trying to schedule several cron jobs to generate serial numbers for different entities within my web app. However I am running into this problem, when I'm looping each table, it says it has something to do with date.js. I'm not doing anything with a date object ? Not at this stage anyway. A couple of guesses is that the cron object is doing a date thing in its code and is referencing date.js. I'm using date.js to get access to things like ISO date.
for (t in config.generatorTables) {
console.log("t = " + config.generatorTables[t] + "\n\n");
var ts3 = azure.createTableService();
var jobSerialNumbers = new cronJob({
//cronTime: '*/' + rndNumber + ' * * * * *',
cronTime: '*/1 * * * * *',
onTick: function () {
//console.log(new Date() + " calling topUpSerialNumbers \n\n");
manageSerialNumbers.topUpSerialNumbers(config.generatorTables[t], function () { });
},
start: false,
timeZone: "America/Los_Angeles"
});
ts3.createTableIfNotExists(config.generatorTables[t], function (error) {
if (error === null) {
var query = azure.TableQuery
.select()
.from(config.generatorTables[t])
.where('PartitionKey eq ?', '0')
ts3.queryEntities(query, function (error, serialNumberEntities) {
if (error === null && serialNumberEntities.length == 0) {
manageSerialNumbers.generateNewNumbers(config.maxNumber, config.serialNumberSize, config.generatorTables[t], function () {
jobSerialNumbers.start();
});
}
else jobSerialNumbers.start();
});
}
});
}
And this is the error message I'm getting when I examine the server.js.logs\0.txt file:
C:\node\w\WebRole1\public\javascripts\date.js:56
onsole.log('isDST'); return this.toString().match(/(E|C|M|P)(S|D)T/)[2] == "D"
^

I am using this line in my database.js file:
require('../public/javascripts/date');
is that correct that I only have to do this once, because date.js is global? I.e. it has a bunch of prototypes (extensions) for the inbuilt date object.
Within manageSerialNumbers.js I am just doing a callback, their is no code executing as I've commented it all out, but still receiving this error.
Any help or advice would be appreciated.
