问题
How would I get my python script to check whether or not a specific timezone that is stored in a variable using DST right now? My server is set to UTC. So I have say for instance
zonename = Pacific/Wallis
I want to run the query about if it is using DST right now and have the reply come back as either true of false.
回答1:
from pytz import timezone
from datetime import datetime
zonename = "Pacific/Wallis"
now = datetime.now(tz=timezone(zonename))
dst_timedelta = now.dst()
### dst_timedelta is offset to the winter time,
### thus timedelta(0) for winter time and timedelta(0, 3600) for DST;
### it returns None if timezone is not set
print "DST" if dst_timedelta else "no DST"
alternative is to use:
now.timetuple().tm_isdst
Which can have one of 3 values: 0 for no DST, 1 for DST and -1 for timezone not set.
