There is no such a function in the whole Harbour and xHarbour repository. Please check the function name.

Hi Richard,

Could this feature be useful to you?

Code: Select all Collapse

SecondsFrom1970()

#pragma BEGINDUMP

#include <time.h>
#include <stdio.h>
#include <stdlib.h>
#include "hbapi.h"

HB_FUNC( SECONDSFROM1970 )

{
        unsigned long count;
        time_t *tmppointer=NULL;
        
        count = time( tmppointer ) ;
        
        hb_retnl( count ) ;
}

#pragma ENDDUMP
