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.
