Optional localtime is a flag that when True, interprets timeval, and returns a date relative to the local timezone instead of UTC, properly taking daylight savings time into account. Optional argument usegmt means that the timezone is written out as an ascii string, not numeric one (so "GMT" instead of "+0000"). This is needed for HTTP, and is only used when localtime==False.

If called without arguments, return current time. Otherwise *dt* argument should be a datetime instance, and it is converted to the local time zone according to the system time zone database. If *dt* is naive (that is, dt.tzinfo is None), it is assumed to be in local time. In this case, a positive or zero value for *isdst* causes localtime to presume initially that summer time (for example, Daylight Saving Time) is or is not (respectively) in effect for the specified time. A negative value for *isdst* causes the localtime() function to attempt to divine whether summer time is in effect for the specified time.
