timezone

问题 I am having a hard time displaying time for a specific timezone. I have a TV Guide like app that gets all start times of the programs in Unix epoch time from the server and I want the times to be shown in the time it would be in the Netherlands wherever the app user is and from whatever android device. After a bit of researching I would think it would work like this: new SimpleDateFormat("HH:mm", new Locale("nl", "NL")).format(new Date(time*1000)); where time is a epoch time for example

问题 Using pure javascript (no jquery nor plugins), how do I convert one local time to another timezone? For situation: I am doing a countdown timer and I've set the end date as a javascript variable. I want to convert that variable to a local time depending on the client location/time zone. var maintenanceEndDate = new Date("11/10/2015 00:00"); //This is the initial time, based on the administrator's location var maintenanceEndDateOffset = ???? //The above time converted to local time and THEN I

问题 I declared Calendar and SimpleDateFormat like this: calendar = Calendar.getInstance(TimeZone.getTimeZone("Malaysia")); final SimpleDateFormat sdf = new SimpleDateFormat("yyyy.MMMMM.dd hh:mm aaa"); or: calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT+08:00")); Then I call this: sdf.format(calendar.getTime()); but result is not in correct time zone (+8 hours). What could be the problem? 回答1: Unless you are going to perform Date/Time related calculations, there is no point in

问题 I am looking for the way to convert cron expression from one timezone to another one timezone. For example, my web-client user is GMT+1200 and my server-side is GMT+0800, while user setting 02:10 to execute task every Tuesday and Thursday, the cron expression will be "0 10 2 3,5 * ?", and I have used code as below, it can get current fire time for user's timezone CronExpression expr = new CronExpression("0 10 2 3,5 * ?"); System.out.println(expr.getNextValidTimeAfter(new Date())); System.out

问题 I want to ask about UNIX time, Does UNIX time record Timezone? I moved my hosting from Chicago/America to JST. The problem is that my whole MySQL database has records of UNIX time (Chicago/America timezone) I have a PHP code to show the time ago (ex 3days ago, yesterday, etc) When I move to the new server it says tomorrow To avoid this tomorrow, is it ok to make the server down for one day in order to synchronize with the current server's timezone? I worry that the UNIX time doesn't only

问题 Strangely, TimeZone.CurrentTimeZone.StandardName returns localized name as per computer display language. I want a programmatic identifier that I can provide to TimeZoneInfo in following code. TimeZoneInfo timeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById(timeZone); FindSystemTimeZoneById expects a unique un-localized programmatic identifier I changed my computer display language to Chinese and I was getting a localized unicode string when I do TimeZone.CurrentTimeZone.StandardName . However

问题 I am relative new to Flutter. While I was experimenting, I came across with an issue. My REST Api takes a timezone parameter (Zone ID format such as Europe/London). I saw both https://pub.dartlang.org/packages/flutter_native_timezone and https://pub.dartlang.org/packages/timezone, but neither of those serve my needs. My goal is, when the user connect to the internet (without giving any location access to the app, if it is possible), get the timezone in ZoneId format and feed my back end in

问题 So I have read https://cloudplatform.googleblog.com/2014/03/geoip-geolocation-with-google-bigquery.html But I was wondering if there was a #standardSQL way of doing it. So far, I have a lot of challenge converting PARSE_IP and NTH() since the suggested changes in the migration docs have limitations. Going from PARSE_IP(contributor_ip) to NET.IPV4_TO_INT64(NET.SAFE_IP_FROM_STRING(contributor_ip)) does not work for IPv6 IP addresses. Going from NTH(1, latitude) lat to latitude[SAFE_ORDINAL(1)]
