datetime - Python: date, time formatting

Question

I need to generate a local timestamp in a form of YYYYMMDDHHmmSSOHH'mm'. That OHH'mm' is one of +, -, Z and then there are hourhs and minutes followed by '.

Please, how do I get such a timestamp, denoting both local time zone and possible daylight saving?

Answer 1

import time

localtime   = time.localtime()
timeString  = time.strftime("%Y%m%d%H%M%S", localtime)

# is DST in effect?
timezone    = -(time.altzone if localtime.tm_isdst else time.timezone)
timeString += "Z" if timezone == 0 else "+" if timezone > 0 else "-"
timeString += time.strftime("%H'%M'", time.gmtime(abs(timezone)))
