dst

This question is related to this one , but is kept more general and can be treated independently. EDIT: Quartz version is v2.0.1 From my understanding, the following unit test should pass: [Test] public void Test() { // run every first day of month at 14:00 hours CronExpression expression = new CronExpression("0 0 14 1 * ?"); // TimeZoneInfo.Local = {(UTC+01:00) Amsterdam, Berlin, Bern, Rom, Stockholm, Wien} if (!TimeZoneInfo.Local.SupportsDaylightSavingTime) { return; } // get "summertime" period for current timezone var daylightChange = TimeZone.CurrentTimeZone.GetDaylightChanges(2013); // -

(I am new to Python and Google App Engine, please forgive me if my questions seem basic). I'm having a helluva time trying to manage multiple user timezones in my Google App Engine application. Here are my constraints: If a user enters the time on an input, it will be local time (including DST, when appropriate). If a user does not enter the time, the system must enter it for them in their local time (including DST, when appropriate). When the date and time are displayed to the user, it must be in their local time (including DST, when appropriate) I understand that time will be internally

I need to write a web application that show events of people in different locale. I almost finished it, but there're 2 problems with date: using date javascript object, the date depends on user computer settings and it's not reliable if there's an event in a place with dfferent timezone respect user current position, i have to print it inside () . Is it possible in javascript to build a date object with a given timezone and daylight settings? I also find some workaround, such as jsdate and date webservices, but they don't overcome the problem of having a javascript object with the correct

In C, is there a simple, cross-platform way of retrieving the dates that a given timezone begins and ends daylight saving? I already have timezone offset information and whether or not daylight savings is currently being observed, but I really need the dates at which daylight savings begins and ends (for an external dependency I don't control). In Windows, I'm using GetTimeZoneInformation to get TimeZoneInfo , but I can't find a similar function for Linux/Solaris/Mac. I should point out also that I can't just rely on US rules for daylight savings adoption, as I can't predict the countries it

This question already has an answer here: get the DST boundaries of a given timezone in python 1 answer I'm looking for a method of determining when DST starts or ends for a given timezone in a Python script I'm working on. I know pytz can convert the UTC dates I'm working into localtime, and will take DST into account, however for this particular application I need to know the point of the changeover. Any suggestions? You could have a look to the _utc_transition_times memberof the timezone you're using. >>> from pytz import timezone >>> tz = timezone("Europe/Paris") >>> print tz._utc

I'm using JodaTime 2.1 and I'm looking for a pattern to unit test code which performs date/time operations to make sure it behaves well for all time zones and independent of DST . Specifically: How can I mock the system clock (so I don't have to mock all the places where I call new DateTime() to get the current time) How can I do the same for the default time zone? You can use a @Rule for this. Here is the code for the rule: import org.joda.time.DateTimeZone; import org.junit.rules.TestWatcher; import org.junit.runner.Description; public class UTCRule extends TestWatcher { private DateTimeZone
