%z
поддерживается в Python 3.2 +:
>>> from datetime import datetime
>>> datetime.strptime('2009/05/13 19:19:30 -0400', '%Y/%m/%d %H:%M:%S %z')
datetime.datetime(2009, 5, 13, 19, 19, 30,
tzinfo=datetime.timezone(datetime.timedelta(-1, 72000)))
В более ранних версиях:
from datetime import datetime
date_str = '2009/05/13 19:19:30 -0400'
naive_date_str, _, offset_str = date_str.rpartition(' ')
naive_dt = datetime.strptime(naive_date_str, '%Y/%m/%d %H:%M:%S')
offset = int(offset_str[-4:-2])*60 + int(offset_str[-2:])
if offset_str[0] == "-":
offset = -offset
dt = naive_dt.replace(tzinfo=FixedOffset(offset))
print(repr(dt))
# -> datetime.datetime(2009, 5, 13, 19, 19, 30, tzinfo=FixedOffset(-240))
print(dt)
# -> 2009-05-13 19:19:30-04:00
, где FixedOffset
- класс, основанный на примере кода из документов :
from datetime import timedelta, tzinfo
class FixedOffset(tzinfo):
"""Fixed offset in minutes: `time = utc_time + utc_offset`."""
def __init__(self, offset):
self.__offset = timedelta(minutes=offset)
hours, minutes = divmod(offset, 60)
#NOTE: the last part is to remind about deprecated POSIX GMT+h timezones
# that have the opposite sign in the name;
# the corresponding numeric value is not used e.g., no minutes
self.__name = '<%+03d%02d>%+d' % (hours, minutes, -hours)
def utcoffset(self, dt=None):
return self.__offset
def tzname(self, dt=None):
return self.__name
def dst(self, dt=None):
return timedelta(0)
def __repr__(self):
return 'FixedOffset(%d)' % (self.utcoffset().total_seconds() / 60)
