Not the same. NTP is a seperate internet protocol

Hi,
No experience with this service but I note that it limits the frequency with which it can be accessed. In practice I think most services do this so, depending on how intensely the application is used, getting the time directly from an Internet server every time someone clocks in or out may not be practical. If the workstation is part of a network then the best compromise may be to get the time from another machine each time it is needed and to update that machine from the internet every, say, couple of hours.

Foxpro code for the NetRemoteTOD API suggested by Chuck is here:http://support.microsoft.com/kb/249716

A possible time source for your own time server might NTP from one of the NIST time servers. Information and a simple piece of public domain software to sync the clock automatically at a specified interval here:http://tf.nist.gov/service/its.htm
