>>> datetime.strptime("Mon,   9\t\t\tAug\n2014\r7:36:46\f-0700", "%a, %d %b %Y %H:%M:%S %z")
datetime.datetime(2014, 8, 9, 7, 36, 46,
tzinfo=datetime.timezone(datetime.timedelta(-1, 61200)))

strptime doesn't seem to care about variations in whitespace as long
as some is present, or missing leading zeroes (although it does throw
an error if the time zone offset is only 3 digits).
