Timestamp conversion is off by an hour

Question

I'm trying to parse a twitter feed in django, and I'm having a strange problem converting the published time:

I've got the time from the feed into a full 9-tuple correctly:

>> print tweet_time
time.struct_time(tm_year=2009, tm_mon=6, tm_mday=17, tm_hour=14, tm_min=35, tm_sec=28, tm_wday=2, tm_yday=168, tm_isdst=0)

But when I call this:

tweet_time = datetime.fromtimestamp(time.mktime(tweet_time))

I end up with the a time 1 hour ahead:

>> print tweet_time
2009-06-17 15:35:28

What am I missing here?

Answer 1

try flipping the isdst (is daylight savings flag) to a -1 and see if that fixes it. -1 tells it to use (guess) the local daylight savings setting and roll with that.
