Python daylight savings time

Question

How do I check if daylight saving time is in effect?

Answer 1

You can use time.localtime and look at the tm_isdst flag in the return value.

>>> import time
>>> time.localtime()
(2010, 5, 21, 21, 48, 51, 4, 141, 0)
>>> _.tm_isdst
0

Using time.localtime(), you can ask the same question for any arbitrary time to see whether DST would be (or was) in effect for your current time zone.
