interval can be updated.
If it has been installed with other time synchronization software, you need to uninstall the software and
restart the computer. The windows time service can work normally.
For Win2000/98 operating system, the time synchronization software provided by our firm or provided by
the third-party are both available. The
specific configuration can be referred to the respective user

For UNIX systems, in general, there is ntpd daemon or xntpd daemon. Create the ntp.conf configuration
file under the / ETC directory and type "server ******" ( time server IP) in it. Then starting the daemon will
do.
