A customer wants to have a row of clocks showing different timezones.
Unfortunately the clock widget doesn't handle that case very well.
But a little simple hackery should suffice.  Changes follow.  This
is relative to R4/lib/Xaw/Clock{.c,P.h,.h} distributed from MIT and
patched to patchlevel 18.

--------------> Clock.c <-------------
static XtResource resources[] = {
	...
    {XtNhourOffset, XtCInterval, XtRInt, sizeof(int),
        offset(hourOffset), XtRImmediate, (caddr_t) 0 },
};
...
/* ARGSUSED */
static void Initialize (request, new)
    Widget request, new;
{
...
    while (w->clock.hourOffset > 12)    /* Normalize the offset */
        w->clock.hourOffset -= 12;
    while (w->clock.hourOffset < -12)
        w->clock.hourOffset += 12;
...
}
...
/* ARGSUSED */
static void clock_tic(client_data, id)
        caddr_t client_data;
        XtIntervalId *id;
{
...
        (void) time(&time_value);
        time_value += (w->clock.hourOffset * 60 * 60);
        tm = *localtime(&time_value);
...
}

--------------> Clock.h <-------------

/* Parameters:
...
 hourOffset          Interval           int             0  (hours)
...
*/
...
                /* Int: Value to add to the hours, half-assed way to display different timezones */
#define XtNhourOffset "hourOffset"


--------------> ClockP.h <-------------

/* New fields for the clock widget instance record */
typedef struct {
...
         int    hourOffset;     /* How much to offset the hours ... */
...
   } ClockPart;
