DateTime in ISO 8601 + TimeZone and without microseconds

Question

I need date-time string in ISO 8601 without any microseconds.

Like:

2015-01-05T11:26:00-03:00

I use:

from pytz import timezone
from datetime import datetime
timezone(settings.TIME_ZONE).localize(datetime.now()).isoformat()

But it returns:

'2015-01-28T17:49:39.711725-03:00'

How to fix that?

to get the current localized time, use `datetime.now(timezone(settings.TIME_ZONE))`. Do not use `.localize(naive_local_time)` -- local time may be ambiguous e.g., during end-of-DST transitions. `now(timezone(settings.TIME_ZONE))` always works because it uses `fromutc()` internally while `.localize()` may return a wrong result for ambiguous or non-existent local time. — jfs, Jan 28 '15 at 15:56

t = timezone(settings.TIME_ZONE).localize(datetime.now()).replace(microsecond=0)
t.isoformat()

datetime.datetime.replace(...) will return a new datetime object with specified attribute modified.
