rdate
A protocol to retrieve the date and time from a time server.
It will query a URL of an RFC 868 time server.
rdate://servername
And return a date in the format of:
DDD MMM DD HH:MM:SS YYYY
Network operations require time synchronized information to ensure optimal network performance.
Computer clocks are notorious for drifting. So it's a very good idea to set up time synchronization. You will need root privileges to do this.
See the manual: date and netdate.
