Synchronize time on 2 computers not connected to the internet or nay network

[chetanh]

Hi,
I have 2 Windows XP Professional SP2 computers. They are running
applications that need the time on the two computers be always
synchronized. The two computers are

1) Not connected to the internet.
2) Not a part of the domain and are not connected to any network.
3) They are connected to each other using a cross cable.

Can i set up one of the XP SP2 computers as a time server. This
computer can be set to synchronize with the CMOS clock on the
motherboard. Once done that is there a way i can point the other
computer to synchronize its clock with the first computers. I dont
know if this can be done and if yes then how?

Ofcourse i have other options like connecting both computers to the
internet and syncing them to a time server but i would like to avoid
spending money on a DSL connection (Both computers have modems which
are in use 24*7)

Another option i have is to buy two GPS time sync receivers and have
the computers synced up. Again that costs money and i would like to
not buy it if possible.


Any suggestion ideas would be welcome. I am open to installing
freeware applications on the computer to make this work

Thanks

*** Why not keep it simple and run this command on the slave PC

*** net time \\MasterPC /set /yes

Thanks for your suggestion. I can set this command to run (net time \
\MasterPC /set /yes) as a scheduled task, but will the slave computer
be able to pull time from the master as it is a XP computer and not a
2K3 server, does XP has a time servier built in.

thanks

The "net time" command just synchronizes the clock on the machine the
command is run on with the clock of the machine the command is run against.
No time server is involved (or needed).

Use of a time server is used to ensure the clock is always correct, so
typically you'd want to make sure the master PC is always correct (which you
really won't be able to do without it synching with a time server).

Perhaps when you occasionally get online with the Master machine you can
sync your time manually, as it will eventually drift out of sync with
regular time (particularly as the battery loses it's oomph).

Tried it and it works perfect. Thanks for your replies.
