Here's the one used in the Xforms port to VMS.  I don't recall who wrote it 
originally, though, and I don't know if it will work with Gnu C.  (This was
done before gettimeofday made it into the DEC C RTL.)  Are you sure Gnu C
doesn't have gettimeofday - maybe you just need to define something
to pick it up????

*******gettimeofday.c*************
#include <timeb.h>

int
gettimeofday(struct timeval *tv, struct timezone *tz)
{
    timeb_t tmp_time;

    ftime(&tmp_time);

    if (tv != NULL)
    {
        tv->tv_sec = tmp_time.time;
        tv->tv_usec = tmp_time.millitm * 1000;
    }
    if (tz != NULL)
    {
        tz->tz_minuteswest = tmp_time.timezone;
        tz->tz_dsttime = tmp_time.dstflag;
    }

    return (0);

}                               /*** End gettimeofday() ***/
