timezone

问题 Ideally, what I'd like to be able to do is take the name of a time zone and ask Windows for its corresponding time zone info (offset from UTC, DST offset, dates for DST switch, etc.). It looks like Windows uses a TIME_ZONE_INFORMATION struct to hold this sort of info. So, presumably, I want a function which takes a string with the time zone's name and returns a TIME_ZONE_INFORMATION struct. However, all I can find are functions such as GetTimeZoneInformation() which give me the TIME_ZONE

问题 Input String: June 14, 2012 - 01:00:00 UTC Output Local String: Jun 13, 2012 - 21:00:00 EDT I like to get the offset from NSTimeZone* destinationTimeZone = [NSTimeZone systemTimeZone]; NSLog(@"Time Zone: %@", destinationTimeZone.abbreviation); Any suggestion ? 回答1: This should do what you need: NSDateFormatter *fmt = [[NSDateFormatter alloc] init]; fmt.dateFormat = @"LLL d, yyyy - HH:mm:ss zzz"; NSDate *utc = [fmt dateFromString:@"June 14, 2012 - 01:00:00 UTC"]; fmt.timeZone = [NSTimeZone

问题 following How to store date/time and timestamps in UTC time zone with JPA and Hibernate I want to set my application default time zone to UTC. My app runs on tomcat on a linux server along side some other apps. The server has other tomcat instances that run even more apps. Will Timezone.setDefault(tz) affect the other apps on the same tomcat instance? Will it affect other apps on other tomcat instances? Is it possible to set the timezone only for the app? I loosely remember something about

问题 I'm working on porting a .NET Framework 4.5 app to .NET Core 2.0 and have started to do some testing on my Mac. When I run this code on .NET Core 2.0 on Windows it works fine: TimeZoneInfo.FindSystemTimeZoneById("Pacific Standard Time"); but it throws the following exception on the Mac: System.TimeZoneNotFoundException: The time zone ID 'Pacific Standard Time' was not found on the local computer. ---> System.IO.FileNotFoundException: Could not find file '/usr/share/zoneinfo/Pacific Standard

问题 This should be very simple, but I can't quite figure it out in Python. I want to have a function which takes two arguments, a UTC time in seconds and a zoneinfo name like 'Europe/Vienna' and returns the offset in seconds from local time and UTC for that point in time. In C it would be: /* ... code to to set local time to the time zone I want to compare against, not shown here. Then call function below to get difference vs localtime. Hardly an ideal solution, but just to demonstrate what I

问题 I'm using GoogleCharts to draw a line chart with a 'datetime' type along one axis. I'd like to format the axis labels so that they display times in a specified timezone instead of the default browser timezone. From reading the documentation, there is a DateFormat object which can be supplied with a 'timeZone' option, and then called with the appropriate DataTable and column to format all cells in that column. I've noticed that doing this results in values that are correctly formatted if the

问题 I'm trying to get a TimeZone for a user. For this I have a country code which is a valid ISO Country Code. These codes are the upper-case, two-letter codes as defined by ISO-3166. You can find a full list of these codes at a number of sites, such as: http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html I think the response is "no because it's a manytomany relationship... there can be many timezone for a country like USA ...". That's the problem... I've tryied something like: //CountryEnum
