timezone

问题 Could you please shed some light on how to obtain correct epoch time in milliseconds for a default system timezone and given timezone. Given 1. TimeZone: GMT+3 2. The following code snippet: import java.time.*; public class Main { public static void main(String[] args) { System.out.println(LocalDateTime .now() .atZone(ZoneOffset.UTC) .toInstant() .toEpochMilli() ); System.out.println(LocalDateTime .now() .atZone(ZoneOffset.of("+3")) .toInstant() .toEpochMilli() ); System.out.println(System

问题 Confused with the use of General time zone('z'). Joda is failing in below sample code. Can somebody help me to understand why the behavior is like this? How can I parse a date in differnt timezone using this format in Joda? public static void main(String[] args) throws ParseException { SimpleDateFormat sdf = new SimpleDateFormat("yyyy.MM.dd G 'at' HH:mm:ss z"); System.out.println(sdf.parse("2019.09.17 AD at 15:29:00 IST")); DateTimeFormatter pattern = DateTimeFormat.forPattern("yyyy.MM.dd G

问题 Given an arbitrary time offset, how does one go about creating a usable time.Location object that represents that time offset? The following code parses a time using an offset, but fmt.Println(t.Location()) subsequently returns no information: func main() { offset := "+1100" t, err := time.Parse("15:04 GMT-0700","15:06 GMT"+offset) if err != nil { fmt.Println("fail", err) } fmt.Println(t) fmt.Println(t.UTC()) fmt.Println(t.Location()) } Playground: https://play.golang.org/p/j_E28qJ8Vgy

问题 I have an X.509 certificate which has the following 2 timestamps: ['validFrom'] = String(13) "120314165227Z" ['validTo'] = String(13) "130314165227Z" What does the postfix character 'Z' mean. Does it specify the timezone? 回答1: Yes. 'Z' stands for Zulu time, which is also GMT and UTC. From http://en.wikipedia.org/wiki/Coordinated_Universal_Time: The UTC time zone is sometimes denoted by the letter Z—a reference to the equivalent nautical time zone (GMT), which has been denoted by a Z since

问题 How can I get time zones list in Microsoft SQL Server 2008R2? 回答1: Using time zone data in SQL Server 2008 http://blogs.msdn.com/b/sqlprogrammability/archive/2008/03/18/using-time-zone-data-in-sql-server-2008.aspx. If I understand the blog entry correctly, there is no time zones list in SQL Server 2008 R2, because there is no internationally recognized standard for such a list. Instead, Microsoft offers a datetimeoffset data type, which allows you to work with numeric time zone offsets.

问题 I am using the below code to cast time as UTC which is working import java.text.SimpleDateFormat; import static java.util.Calendar.* def dt = "2018-03-19T06:00:00+01:00" def format = "yyyy-MM-dd'T'HH:mm:ssX" TimeZone tz = TimeZone.getDefault(); //getting up local time zone TimeZone.setDefault(TimeZone.getTimeZone("UTC")); SimpleDateFormat sdf = new SimpleDateFormat(format); Date d = sdf.parse(dt); TimeZone.setDefault(tz); println d //output: 2018-03-19T05:00:00Z println d.toTimestamp(); /

问题 I'm wondering how to go about changing the timezone of a DateTime object without actually changing the value. Here is the background... I have an ASP.NET MVC site hosted on AppHarbor and the server has its time set to UTC. When I submit a form from my site containing a datetime value, say 9/17/2013 4:00am, it comes up to the server with that value. However then when I do: public ActionResult Save(Entity entity) { entity.Date = entity.Date.ToUniversalTime(); EntityService.Save(entity); } ...it

问题 I am having trouble understanding Rails' time zone support when it comes to daylight savings time. I am storing all database times in UTC . User timezones are stored so that they map directly back to ActiveSupport::TimeZone values (i.e. Central Time (US & Canada) ). I want to completely ignore daylight savings time. If an event starts at 5:30pm , it always starts at 5:30pm whether daylight savings time is in effect or not. Is it possible, considering all times are stored uniformly, to
