Firstly , I should clarify I have no idea how to program python, I joined
this mailing list in anticipation of learning soon. And thought I'd have a
go playing around with your code and code given to you (worst possible
place to start, I'm sure)
But from the answers already given to you, this seems to work and as you
requested, in reality, this keeps your code to 1 line...
I'm sure this is wrong, and isn't what you want, but hey, Correct working
code doesn't seem to matter to you anyway...
(I think "Europe/Kiev" is Greece but I don't know)
from datetime import datetime, time, timedelta
import time
import pytz
def is_dst(zonename):
tz = pytz.timezone(zonename)
now = pytz.utc.localize(datetime.utcnow())
return now.astimezone(tz).dst() != timedelta(0)
def dst_greece():
if is_dst("Europe/Kiev") :
diff = 2
else:
diff = 3
return diff
lastvisit = (datetime.utcnow() +timedelta(hours=dst_greece())).strftime(
'%y-%m-%d %H:%M:%S' )
