If you don’t want to provide your own tzinfo objects, check out the python-dateutil library. It provides tzinfo implementations on top of a zoneinfo (Olson) database such that you can refer to time zone rules by a somewhat canonical name. from datetime import datetime from dateutil import tz # METHOD 1: Hardcode zones: from_zone = … Read more
For strings such as 2012-09-19 01:27:30.000, DateTime.Parse cannot tell what time zone the date and time are from. DateTime has a Kind property, which can have one of three time zone options: Unspecified Local Utc NOTE If you are wishing to represent a date/time other than UTC or your local time zone, then you should … Read more
If d = date(2011, 1, 1) is in UTC: >>> from datetime import datetime, date >>> import calendar >>> timestamp1 = calendar.timegm(d.timetuple()) >>> datetime.utcfromtimestamp(timestamp1) datetime.datetime(2011, 1, 1, 0, 0) If d is in local timezone: >>> import time >>> timestamp2 = time.mktime(d.timetuple()) # DO NOT USE IT WITH UTC DATE >>> datetime.fromtimestamp(timestamp2) datetime.datetime(2011, 1, 1, … Read more
I think I have a simpler solution — set the initial date to the epoch and add UTC units. Say you have a UTC epoch var stored in seconds. How about 1234567890. To convert that to a proper date in the local time zone: var utcSeconds = 1234567890; var d = new Date(0); // The … Read more
First, parse the string into a naive datetime object. This is an instance of datetime.datetime with no attached timezone information. See its documentation. Use the pytz module, which comes with a full list of time zones + UTC. Figure out what the local timezone is, construct a timezone object from it, and manipulate and attach … Read more
Append ‘UTC’ to the string before converting it to a date in javascript: var date = new Date(‘6/29/2011 4:52:48 PM UTC’); date.toString() // “Wed Jun 29 2011 09:52:48 GMT-0700 (PDT)”
Simple and stupid var date = new Date(); var now_utc = Date.UTC(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(), date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds()); console.log(new Date(now_utc)); console.log(date.toISOString());
Summary of answers and other data: (please add yours) Do: Whenever you are referring to an exact moment in time, persist the time according to a unified standard that is not affected by daylight savings. (GMT and UTC are equivalent with this regard, but it is preferred to use the term UTC. Notice that UTC … Read more
