The NTP code is freely available, but it's rather big for what it does -- I doubt it would fit in one segment, and existing code is a lot of work to segment.

In summary, you'd have to write, or heavily adapt, the code yourself.

Hello, Jeff!
Any suggestion for a free (or not) program that does network time sync?

Time is set during sync when the PC sends a 'set time request' to the DLServer on the Palm device. The DLServer receives time from the PC as {year,month,day,hour,minute,second} and sets the PalmOS system time to the second. Assuming the PC sends it's time near the end of a second, then the PalmOS time and PC time can differ by nearly a whole second. Add any delay between the time the PC actually samples it's time and time the DLServer actually handles the set time request. It could easily be several seconds difference.

Network time synchronization (not HotSync) uses a different protocol, and is capable of much greater accuracy.

Hello!
I tried to sync my Palm device's date/time with the PC's clock.
There still is at least one second of mismatch, maybe more.
AFAIK, time sync with time servers is supposed to be 10 ms precise (according to Wikipedia).

What is the precision of the Palm OS internal clock? For Palm OS 4.x devices (33 MHZ and slower) and for Palm OS 5.x ARM?
How about Palm OS 3.3/3.5?
Does it matter if it syncs via HotSync, or via Internet?

Thanks,
