In the python doc , https://docs.python.org/3.4/library/datetime.html
A timedelta
<https://docs.python.org/3.4/library/datetime.html#datetime.timedelta>
object represents a duration, the difference between two dates or times.
/class /datetime.timedelta(/days=0/, /seconds=0/, /microseconds=0/,
/milliseconds=0/, /minutes=0/, /hours=0/, /weeks=0/)
All arguments are optional and default to 0. Arguments may be
integers or floats, and may be positive or negative.
Only /days/, /seconds/ and /microseconds/ are stored internally.
import datetime
t1='Sat, 09 Aug 2014 07:36:46 -0700'
t2='Sat, 09 Aug 2014 07:36:46 +0700'
>>> datetime.datetime.strptime(t1,"%a, %d %b %Y %H:%M:%S %z")
datetime.datetime(2014, 8, 9, 7, 36, 46,
tzinfo=datetime.timezone(datetime.timed
elta(-1, 61200)))
>>> datetime.datetime.strptime(t2,"%a, %d %b %Y %H:%M:%S %z")
datetime.datetime(2014, 8, 9, 7, 36, 46,
tzinfo=datetime.timezone(datetime.timed
elta(0, 25200)))
problem :
t1 is GMT time 2014 00:36:46
t2 is GMT time 2014 14:36:46
datetime.datetime.strptime do not give me the right answer.
