How to control appearance of ‘:’ in time zone offset when parsing/formatting Datetime

Doesn’t look like there is anything built-in (you can use zz, but that leaves out the minutes). You can roll your own by instantiating a DateTimeFormatInfo, setting TimeSeparator to string.Empty and using that as the IFormatProvider when calling DateTime.ToString (and make the call explicit, if it is not already). But frankly, using Replace to remove … Read more

Getting system Timezones in different languages

Changing the CurrentCulture doesn’t work as the information comes from the registry (XP) or from the Multilingual User Interface (MUI) DLL (Vista, Windows 7). On Vista or Windows 7, you may install other languages and change the display language (Region and Language -> Keyboards and languages -> Display language). A reboot is required. This, and … Read more

Get utc offset from timezone in Javascript

It has become possible nowaday with Intl API: The implementation of Intl is based on icu4c. If you dig the source code, you’ll find that timezone name differs per locale, for example: for (const locale of [“ja”, “en”, “fr”]) { const timeZoneName = Intl.DateTimeFormat(locale, { timeZoneName: “short”, timeZone: “Asia/Tokyo”, }) .formatToParts() .find((i) => i.type === … Read more

How do I print a datetime in the local timezone?

As of python 3.6 calling astimezone() without a timezone object defaults to the local zone (docs). This means you don’t need to import tzlocal and can simply do the following: #!/usr/bin/env python3 from datetime import datetime, timezone utc_dt = datetime.now(timezone.utc) print(“Local time {}”.format(utc_dt.astimezone().isoformat())) This script demonstrates a few other ways to show the local timezone … Read more

How to convert Moment.js date to users local timezone?

You do not need to use moment-timezone for this. The main moment.js library has full functionality for working with UTC and the local time zone. var testDateUtc = moment.utc(“2015-01-30 10:00:00”); var localDate = moment(testDateUtc).local(); From there you can use any of the functions you might expect: var s = localDate.format(“YYYY-MM-DD HH:mm:ss”); var d = localDate.toDate(); … Read more

How to get timezone, Language and County Id in flutter by the location of device in flutter?

Flutter locales explained First of all, you should understand the difference between system settings and your application settings: System settings – what the system provides to your app as user preferences for your information.

How to get Unix timestamp in php based on timezone

The answer provided by Volkerk (that says timestamps are meant to be always UTC based) is correct, but if you really need a workaround (to make timezone based timestamps) look at my example. <?php //default timezone $date = new DateTime(null); echo ‘Default timezone: ‘.$date->getTimestamp().'<br />’.”\r\n”; //America/New_York $date = new DateTime(null, new DateTimeZone(‘America/New_York’)); echo ‘America/New_York: ‘.$date->getTimestamp().'<br … Read more

Converting Between Local Times and GMT/UTC in C/C++

You’re supposed to use combinations of gmtime/localtime and timegm/mktime. That should give you the orthogonal tools to do conversions between struct tm and time_t. For UTC/GMT: time_t t; struct tm tm; struct tm * tmp; … t = timegm(&tm); … tmp = gmtime(t); For localtime: t = mktime(&tm); … tmp = localtime(t); All tzset() does … Read more
