You can use TimeZoneInfo.FindSystemTimeZoneById to get the TimeZoneInfo object using the supplied Id, then TimeZoneInfo.GetUtcOffset from that: TimeZoneInfo tzi = TimeZoneInfo.FindSystemTimeZoneById(“US Eastern Standard Time”); TimeSpan offset = tzi.GetUtcOffset( myDateTime);
dateutil‘s parser.parse() accepts as keyword argument tzinfos a dictionary of the kind {‘EST’: -5*3600} (that is, matching the zone name to GMT offset in seconds). So assuming we have that, we can do: >>> import dateutil.parser as dp >>> s=”Sat, 11/01/09 8:00PM” >>> for tz_code in (‘PST’,’PDT’,’MST’,’MDT’,’CST’,’CDT’,’EST’,’EDT’): >>> dt = s+’ ‘+tz_code >>> print dt, … Read more
In environments that fully support IANA time zone identifiers in ECMA-402 (ECMAScript Internationalization API), you can try using a time zone in a DateTimeFormat (or in the options of to toLocaleString) and it will throw an exception if it is not a valid time zone. You can use this to test for validity, but only … Read more
First, make sure you’re familiar with Django’s documentation on timezones, set USE_TZ = True, and install pytz. I don’t quite understand where your date is coming from. If it’s coming from the server as part of their data (i.e. it represents when the tides were measured), it should either be in UTC already or you … Read more
I know this is old but maybe will be helpful since I got into this situation as well: What about using make_aware() ? from datetime import datetime from django.utils.timezone import make_aware date=”22-05-2018″ aware = make_aware(datetime.strptime(date, ‘%d-%m-%Y’)) This will use the currently active timezone (activated by timezone.activate). If no timezone is activated explicitly, it would use … Read more
While MomentJS is a great library, it may not provide a solution for every use case. For example, my server provides dates in UTC, and when the time portion of the date is not saved in the db (because it’s irrelevant), the client receives a string that has a default time of all zeros – … Read more
The maximum difference is at least 26 hours, as there are time zones for GMT-12 all the way to GMT+14. With DST, that may go up to 27 hours.
With tzwhere and pytz: import datetime import pytz from tzwhere import tzwhere tzwhere = tzwhere.tzwhere() timezone_str = tzwhere.tzNameAt(37.3880961, -5.9823299) # Seville coordinates timezone_str #> Europe/Madrid timezone = pytz.timezone(timezone_str) dt = datetime.datetime.now() timezone.utcoffset(dt) #> datetime.timedelta(0, 7200)
