# Setting time and date

(Configuration "System" General view)

## Set the date and time here.

You can set the date and time manually, synchronise them automatically via the ISDN network or synchronise them via a time server (NTP server). We recommend that you use one of the two synchronisation variants.

If you are using IP terminals and want to operate them in tap-proof mode, you need to synchronise the date and time via a time server.

## Synchronise date and time via NTP server

Activate the NTP service (NTP service: ) and enter the time server’s IP address under NTP server. You can also enter the host name, provided you have entered the address of the DNS server during IP addressing of the communication server.
