RDATE(8) | System Manager's Manual | RDATE(8) |
rdate
— set the
system's date from a remote host
rdate |
[-46acnopsv ] host |
rdate
displays and sets the local date and
time from the host name or address given as the argument. The time source
may be an RFC 5905 protocol SNTP/NTP server or an RFC 868 TCP protocol
server, which is usually implemented as a built-in service of
inetd(8). By default,
rdate
uses the RFC 5905 SNTP/NTP protocol.
The options are as follows:
-4
rdate
to use IPv4 addresses only.-6
rdate
to use IPv6 addresses only.-a
-c
-n
-o
-p
-s
-v
To get the legal time in Germany, set the /etc/localtime symlink to /usr/share/zoneinfo/right/Europe/Berlin and issue the following command:
# rdate -v
ptbtime1.ptb.de
The command of course assumes you have a working internet connection and DNS set up to connect to the server at Physikalisch-Technische Bundesanstalt in Braunschweig, Germany.
