FUNCTION
<<localtime>>---convert time to local representation

INDEX
	localtime
INDEX
	localtime_r

SYNOPSIS
	#include <time.h>
	struct tm *localtime(time_t *<[clock]>);
	struct tm *localtime_r(time_t *<[clock]>, struct tm *<[res]>);

DESCRIPTION
<<localtime>> converts the time at <[clock]> into local time, then
converts its representation from the arithmetic representation to the
traditional representation defined by <<struct tm>>.

<<localtime>> constructs the traditional time representation in static
storage; each call to <<gmtime>> or <<localtime>> will overwrite the
information generated by previous calls to either function.

<<mktime>> is the inverse of <<localtime>>.

RETURNS
A pointer to the traditional time representation (<<struct tm>>).

PORTABILITY
ANSI C requires <<localtime>>.

<<localtime>> requires no supporting OS subroutines.
