Timezones

Retrieve timezones by country:

>>> country = Country.objects.get(cca2='ID')
>>> country.timezones.all()
<QuerySet [<Timezone: Asia/Jakarta>, <Timezone: Asia/Jayapura>, <Timezone: Asia/Makassar>, <Timezone: Asia/Pontianak>]>

>>> timezone = country.timezones.get(name='Asia/Makassar')

Use the use the localize() method to localize a naive datetime (datetime with no timezone information):

>>> from datetime import datetime
>>> dtime = datetime(year=2017, month=4, day=2, hour=16, minute=20)
>>> timezone.localize(dtime)
datetime.datetime(2017, 4, 2, 16, 20, tzinfo=<DstTzInfo 'Asia/Makassar' WITA+8:00:00 STD>)

Converting an existing localized time using the standard ``astimezone()`:

>>> utc_dtime = dtime.replace(tzinfo=pytz.utc)
>>> timezone.astimezone(utc_dtime)
datetime.datetime(2017, 4, 3, 0, 20, tzinfo=<DstTzInfo 'Asia/Makassar' WITA+8:00:00 STD>)

Get the current time with now():

>>> from datetime import datetime
>>> timezone = country.timezones.get(name='Asia/Makassar')
>>> timezone.now()
datetime.datetime(2017, 5, 2, 16, 15, 13, 626913, tzinfo=<DstTzInfo 'Asia/Makassar' WITA+8:00:00 STD>)

set the current time zone to the end user’s actual time zone with activate()

>>> timezone.activate()
