timezone

问题 For our Russia tenant we are using "Europe/Moscow" timezone. But we are getting time with 1 hour ahead of the correct time. Europe/Moscow is UTC+3 hours. But when I am print date formated with Europe/Moscow timezone getting 1 hour ahead of the correct time. Thanks, Syamala. 回答1: I notice that there was a legislative change to Russian time zone definitions in October 2014; chances are that your JRE simply doesn't know about it yet. The Java Timezone Updater Utility should be able to fix this

问题 I have one situation where date is "3/13/2016 2:41:00 AM" . When I convert date by time-zone, I get an error. DateTime dt = DateTime.Parse("3/13/2016 2:41:00 AM"); DateTime Date_Time = TimeZoneInfo.ConvertTimeBySystemTimeZoneId(dt, "Eastern Standard Time", "GMT Standard Time"); Response.Write(dt); after execution, I get this error: The supplied DateTime represents an invalid time. For example, when the clock is adjusted forward, any time in the period that is skipped is invalid. Parameter

问题 The documentation for Date.getTimezoneOffset says: Deprecated. As of JDK version 1.1, replaced by -(Calendar.get(Calendar.ZONE_OFFSET) + Calendar.get(Calendar.DST_OFFSET)) / (60 * 1000). Why was it deprecated? Is there a shorter way (Apache Commons?) to get the offset from UTC in hours/minutes? I have a Date object ... should I convert it to JodaDate for this? And before you ask why I want the UTC offset - it's just to log it, nothing more. 回答1: There are 2 questions here. Why was Date

问题 In my project there is drop-down of time zones(PT,CST etc), when Admin changes the timezone from drop-down the admin panel reflects the timezone from the selected drop down.

问题 I have a function that converts from unix epoch time to a .NET DateTime value: public static DateTime FromUnixEpochTime(double unixTime ) { DateTime d = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc); return d.AddSeconds(unixTime); } Where I am (UK) the clocks go one hour forward for summer time. In Python I get the local Epoch time using time.time() (and for the sake of argument, right now the time is 17:15:00) which gives me a value of 1286122500 . If I convert this back to a human

问题 When running some tests I came across the following issue. When using: private String printStandardDate(Date date) { return DateFormat.getDateTimeInstance( DateFormat.SHORT, DateFormat.SHORT).format(date); } I found this produced different formats of Date depending on the location the tests where run from. So locally in windows / eclipse I got a result: 04/02/12 18:18 but on the Linux box in America I get 2/4/12 6:18 PM This causes my Tests/Build to fail: expected:<[04/02/12 18:18]> but was:<

问题 The following query SELECT the_date FROM date_trunc('day', timestamp with time zone '2001-01-1 00:00:00+0100') as the_date results to the_date 2000-12-31 00:00 Is there a way to tell date_trunc to do day/month/year conversions based on the timezone it is feeded with? The expected output would be: 2001-01-1 00:00+0100 回答1: You need to specify at which time zone you want it to show select date_trunc( 'day', timestamp with time zone '2001-01-1 00:00:00+0100' at time zone '-02' ) as the_date; the
