FUNCTION
<<localtime>>---convert time to local representation
INDEX
localtime
INDEX
localtime_r
ANSI_SYNOPSIS
#include <time.h>
struct tm *localtime(time_t *<[clock]>);
struct tm *localtime_r(time_t *<[clock]>, struct tm *<[res]>);
TRAD_SYNOPSIS
#include <time.h>
struct tm *localtime(<[clock]>)
time_t *<[clock]>;
struct tm *localtime(<[clock]>, <[res]>)
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.
