Thanks,
The system ticks count is a monotonically increasing value that could be
used for this purpose. You can convert ticks to seconds by dividing by
the value returned by SysGetTicksPerSecond. You can get the current
tick count via TimGetTicks.
Ticks don't go up when the device is in sleep mode -- that will be a
problem. You could use the sleep and wake notifications on Palm OS 3.5
and later to catch that and adjust your calculations using the
differences in the realtime clock.
Note: this count does get reset by any reset, not just a hard reset, but
its the best thing available on the Palm. Also, the tick count will
overflow after about 497 days on most Palm OS devices, so its possible
that
