>>See my FAQ about this. It's under the WIN32API & Other APIs section. However, the machines must be NT (workstation or server). The API functionality is not supported under Win9X.

There's almost no chance of getting it this way, because the time written in the file is static. The easiest thing to do is to have the local system create a temporary file on the server and immediately read it's creation time - the timestamp for the file uses the server machine's time, so you adjust the time on the local workstation to match the server's time.
