Synchronising Computer Time

Make all computers on your network use the same time..

PCs usually take their time from the CMOS on each machine's individual motherboard. On a MS Windows network you can make individual machines synchronise their time and date with another computer, usually a server [with a reliable clock].

The NET TIME command runs from the Command Prompt window and can be used with operating systems from Windows 95 onwards. Using the usual /? switch after typing the command brings up the switch options for this command:

The following command using NET TIME will immediately synchronise this computer's time and date with the computer whose IP Address is 192.168.0.1:

The NET TIME command can be incorporated into one line of a batch file, exactly as it's typed above [although the IP Address will vary], for ease of operation. For batch files, see PC Operations, MS DOS menu.

Additionally NET TIME can be used with the AT Command, to automate the process completely (Windows NT/2000 and later)
