Is a specific timezone using DST right now?

Question

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 in

Answer 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.
