timezone

问题 I have to import data without time zone information in it (however, I know the specific time zone of the data I want to import), but I need the timestamp with time zone format in the database. Once I import it and set the timestamp data type to timestamp with time zone , Postgres will automatically assume that the data in the table is from my time zone and assign my time zone to it. Unfortunately the data I want to import is not from my time frame, so this does not work. The database also

问题 In listing all the Id properties of the TimeZoneInfo s returned by TimeZoneInfo.GetSystemTimeZones , two versions of EST appear: US Eastern Standard Time and Eastern Standard Time. What's the difference? I also see both US Mountain Standard Time and Mountain Standard Time, but I'm pretty sure that's because the US version is for Arizona, which doesn't observe DST. I'd assume the regular Mountain Standard Time applies for the rest of the US states in the Mountain time zone. Am I correct?

问题 I have a little problem with the Flot plugin while displaying the xaxis labels in the graph. They are 'mode: "time"' . Currently I use Flot with the tooltip function and the tooltip contains a date and time. I supply JSON to the plugin which contains timestamps. Afterwards I convert the timestamp and I display it in the tooltip. The problem is that while displaying the data in the graph, the times from the tooltips don't correspond to the xaxis labels generated by the plugin due to a

问题 This question already has answers here : Parsing date/time string with timezone abbreviated name in Python? (5 answers) Closed 4 years ago . How can I convert a date time string of the form Feb 25 2010, 16:19:20 CET to the unix epoch? Currently my best approach is to use time.strptime() is this: def to_unixepoch(s): # ignore the time zone in strptime a = s.split() b = time.strptime(" ".join(a[:-1]) + " UTC", "%b %d %Y, %H:%M:%S %Z") # this puts the time_tuple(UTC+TZ) to unixepoch(UTC+TZ

问题 I am trying to convert the following timezone to device local timezone: 2013-08-03T05:38:39.590Z Please let me know how to convert it to local timezone. How do I do it? 回答1: Time zones can be applied to NSDateFormatter, from which you can generate NSDate variables differentiated by the time difference. NSString* input = @"2013-08-03T05:38:39.590Z"; NSString* format = @"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"; // Set up an NSDateFormatter for UTC time zone NSDateFormatter* formatterUtc = [

问题 The info pages for the GNU date command contains this example: For example, with the GNU date command you can answer the question "What time is it in New York when a Paris clock shows 6:30am on October 31, 2004?" by using a date beginning with `TZ="Europe/Paris"' as shown in the following shell transcript: $ export TZ="America/New_York" $ date --date='TZ="Europe/Paris" 2004-10-31 06:30' Sun Oct 31 01:30:00 EDT 2004 In this example, the '--date' operand begins with its own 'TZ' setting, so the

问题 This code: DateTimeOffset testDateAndTime = new DateTimeOffset(2008, 5, 1, 8, 6, 32, new TimeSpan(1, 0, 0)); //CLEAN TIME AND DATE testDateAndTime = testDateAndTime.DateTime.Date; var datesTableEntry = db.DatesTable.First(dt => dt.Id == someTestId); datesTableEntry.test= testDateAndTime; db.SaveChangesAsync(); ...produces this result in my database: 2008-05-01 00:00:00.0000000 -04:00 How should I revise my code so that it changes the time zone offset from -4:00 to +00:00 in testDateAndTime ?

问题 I am trying to convert a string timestamp into a proper datetime object. The problem I am having is that there is a timezone offset and everything I am doing doesn't seem to work.
