timezone

问题 Can somebody please explain to me why when I try to get the milliseconds of a DateTime with a zone different from my own, it gives me back the milliseconds of my local machine's time zone? I'm looking to get the milliseconds of UTC, but my local settings of the application are set to EST (even though I'm actually in Ireland ;) ) Here's the code: DateTimeFormatter format = DateTimeFormat.mediumDateTime(); DateTime local = new DateTime(); DateTime utc = new DateTime(System.currentTimeMillis(),

问题 Just adding to the million questions about time zone and DST issues out there. I have a form with separate date and time fields that I combine to create a DateTime like so start_time = DateTime.parse("#{parse_date(form_date)} #{form_start_time} #{Time.zone}") If I fill out my form with 21 Aug 2012 and 15:00, then these are the values that I see when I reload my form. If I then look at my start_time attribute in my model it is correctly set to Tue, 21 Aug 2012 15:00:00 EST +10:00 . The problem

问题 I am using DateTime.Now to show something according to today's date, and when working locally (Malta, Europe) the times appear correctly (obviously because of the Time Zone) but ofcourse when I upload it to my hosting server (USA), DateTime.Now does not represent the correct time zone. Therefore, in my code, how can I convert DateTime.Now to correctly return the time from a GMT + 1 timezone ? 回答1: Use the TimeZoneInfo class found in System.Core; You must set the DateTimeKind to DateTimeKind

问题 I am adding auction-based data to my system. For example: user's timezone is : `America/Denver` auction start time is : Thu, 21 Jun 2012 03:46:22 AM auction period : 1 day. auction end time : Fri, 22 Jun 2012 03:46:22 AM I store all these information as it is in my DB (i.e. all stored time based on user's timezone ). Now I want the actual difference between end time and current time (of America/Denver timezone). I used DateTime() functions so even I don't convert the timezone; it returns same

问题 Want to know whether its possible to change the time of the iPhone through an application.. Is that level of dev access granted in iOS4? My gut feeling is no, but I'm looking for a definitive Yes/No answer if possible. Note: NSTimeZone class states 'Cocoa does not provide any API to change the time zone of the computer, or of other applications.' Thanks.. 回答1: No this functionality is not possible via the official iphone SDK. 来源： https://stackoverflow.com/questions/3121287/can-we-change-the

问题 I want to get local time of different time zones using Java code. Based on the time zone passed to the function I need that time zone's local time. How to achieve this? 回答1: java.util.TimeZone tz = java.util.TimeZone.getTimeZone("GMT+1"); java.util.Calendar c = java.util.Calendar.getInstance(tz); System.out.println(c.get(java.util.Calendar.HOUR_OF_DAY)+":"+c.get(java.util.Calendar.MINUTE)+":"+c.get(java.util.Calendar.SECOND)); 回答2: I'd encourage you to check out Joda Time, an alternative (but

问题 What I need is a time difference between specific timezone ("Russia/Moscow") and local time of the user, difference should be in hours.
