timezone

问题 I just want to clarify if I am understanding how dates & time zones work. Basically, I have a date string @"2008-07-06 12:08:49" that I want to convert to an NSDate. I want this date and time to be in whatever the current user's time zone is set in. So if they are in GMT or HST, it's still 12:08:49. If I have date in unix form 1215382129 (UTC) and my time zone is set to London (GMT), the outputted date from NSLog() is: 2008-07-06 12:08:49 +0100 If I then change my time zone to Hawaii (HST)

问题 I have a custom validation attribute in my ASP.NET Web API application that checks if the date is in the future or not (dates in the future are not allowed). Here's the code: protected override ValidationResult IsValid(object value, ValidationContext validationContext) { if (value != null) { var date = (DateTime)value; if (date != null) { if(date.Date > DateTime.UtcNow.Date) { return new ValidationResult(FormatErrorMessage(validationContext.DisplayName), new[] { validationContext.MemberName }

问题 I having an column of UNIX time stamp in my database table, which comes from a system that is in the Kuwait time zone. My database server's time zone is Eastern Time US & Canada . Now I need to convert the UNIX time stamp in to Kuwait time zone date value using an SQL query. Can anyone tell me how I can convert this UNIX time stamp into a Kuwait time zone date value? 回答1: Unix timestamps are integer number of seconds since Jan 1st 1970 UTC. Assuming you mean you have an integer column in your

问题 public static void main(String[] args) { Timestamp ts = new Timestamp(116, 02, 12, 20, 45, 0, 0); Date d = new Date(); d.setTime(ts.getTime()); System.out.println(d); SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); simpleDateFormat.setTimeZone(TimeZone.getTimeZone("UTC")); //System.out.println(ts.getTime()); System.out.println(simpleDateFormat.format(ts)); System.out.println(Timestamp.valueOf(simpleDateFormat.format(ts))); } In above code last two lines print

问题 I'm facing the following problem, I have a play application with angular and java. In one page the client selects in a calendar some date and time for example 2015-04-03 15:00 this data is put in a javascript object as a Date and later this data is submit to my server but it seams the server is converting this date/time to his timezone saving 2015-04-03 16:00 instead of 15:00 as the client side sent. After I submit the data to the server where is persisted in the database when I reload the

问题 Have been beating my head against this and not sure what I'm doing wrong here. I am testing out the inDaylightTime() method for a certain time zone but it is returning "false" when it should be returning "true" in this case. import java.util.TimeZone; import java.util.Date; public class TimeZoneDemo { public static void main( String args[] ){ Date date = new Date(1380931200); // Sat, 05 Oct 2013, within daylight savings time. System.out.println("In daylight saving time: " + TimeZone

问题 I'm trying to change default timezone in Rails 3.2.8 app to GMT+04:00, but I don't know how to do it. The following solutions do not work for me: config.time_zone = 'Moscow' config.time_zone = "(GMT+04:00) Moscow" config.active_record.default_timezone = 'Moscow' config.active_record.default_timezone = :local Also I've tried in rails console the following: ActiveSupport::TimeZone.all.map(&:name) wich returned a list of values, including "Moscow" . Time.zone returned (GMT+00:00) UTC wich is not

问题 i was wondering if there is a quite simple solution to display content between certain hours and only during working days in a Europe timezone? The hours will be everyday (except weekends) between 9AM and 5PM, between those times a html content should be shown. If possible a different html content from 5PM till 9AM. 回答1: The short version is that you use new Date() to get the current date/time, and then you use DOM manipulation to add/remove that content as appropriate. If you want content to

问题 I'm using SQLite for my cgi application, but the timezone I'm in is different from that of the shared server this stuff is running on. Can I set my timezone somehow in SQLite so I don't need to mess up my application with time conversions and I can use things like NOW() in my SQL? If not: what are my other options? 回答1: SQLite doesn't have a way to set the connection time zone because it's targeted towards embedded database uses--whatever you use to change your C library localtime() output

问题 The author of Searchlogic says that it is delegated to A::R converter, but at least in our case this didn't cover the usual cases. Local time was 'interpreted' as UTC and therefore was moved by one hour (CET). How can I do that properly? I add our current workaround as an answer, hopefully it helps somebody! 回答1: We've added the following method to the application controller: protected def parse_datetime_fields(hash, key) value = hash[key] return unless value hash[key] = Time.zone.parse(value
