converting datetime object in UTC to local time

[Matt]

Hi all,

So a lot of digging on doing this and still not a fabulous solution:

import time

# this takes the last_modified_date naive datetime, converts it to a
# UTC timetuple, converts that to a timestamp (seconds since the
# epoch), subtracts the timezone offset (in seconds), and then
converts
# that back into a timetuple... Must be an easier way...
mytime = time.localtime(time.mktime(last_modified_date.utctimetuple())
- time.timezone)

lm_date_str = time.strftime("%m/%d/%Y %I:%M %p %Z", mytime)

last_modified_date is a naive datetime.datetime object


A previous version gave me something like:

mytime =
datetime.datetime.fromtimestamp(time.mktime(last_modified_date.utctimetuple())
- time.timezone)

lm_date_str = mytime.strftime("%m/%d/%Y %I:%M %p %Z")

But this gave me no timezone since the datetime object is still
naive. And I'm going from a datetime to a timetuple to a timestamp
back to a datetime...

All this seems like a lot of monkeying around to do something that
should be simple -- is there a simple way to do this without requiring
some other module?

thx

Matt

How about subclass datetime.tzinfo? That way you can use asttimezone
to transfer utc to localtime. It requires an aware object though not
naive. A bit more coding, but a lot less converting...
