New submission from akira:
cert_time_to_seconds() uses `time.mktime()` [1] to convert utc time tuple to
seconds since epoch. `mktime()` works with local time. It should use
`calendar.timegm()` analog instead.
Example from the docs [2] is seven hours off (it shows utc offset of the local
timezone of the person who created it):
>>> import ssl
>>> ssl.cert_time_to_seconds("May 9 00:00:00 2007 GMT")
1178694000.0
It should be `1178668800`:
>>> from datetime import datetime
>>> datetime.utcfromtimestamp(1178668800)
datetime.datetime(2007, 5, 9, 0, 0)
>>> import time
>>> time.gmtime(1178668800)
time.struct_time(tm_year=2007, tm_mon=5, tm_mday=9, tm_hour=0, tm_min=0,
tm_sec=0, tm_wday=2, tm_yday=129, tm_isdst=0)
And `calendar.timegm` returns correct result:
>>> calendar.timegm(time.strptime("May 9 00:00:00 2007 GMT", "%b %d
%H:%M:%S %Y GMT"))
1178668800
