Very Computer

As I want to work in multi_threaded design with different time-zone, one

per each thread, I can't use the unix standard fonctions like mktime. I
need a thread-safe function that converts a local-time attached to its
timezone into a GMT time as follow:

    void localtime_to_gmt(const char * timezone,  const struct tm
localtime,  time_t * gmt_time);

Is there a  sofftware which uses instead of TZ env variable a local time

zone variable attached to the process to convert a local time to GMT ?

Thanks for your help ?

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

main()
{
        time_t lt;
        struct tm       gmt;

        lt = time((time_t *) NULL);
        gmtime_r(&lt, &gmt);
