How do I convert a datetime string in local time to a string in UTC time?

Answer 1

def local_to_utc(t):
    secs = time.mktime(t)
    return time.gmtime(secs)

def utc_to_local(t):
    secs = calendar.timegm(t)
    return time.localtime(secs)

Example usage from bd808: If your source is a datetime.datetime object t, call as:

local_to_utc(t.timetuple())
