One Day One GNU/Linux Command
=============================
rdate -- Get the time from Remote machine.
Summary :
It connects to an Remote Time Server over a IP network, printing the
returned time and/or setting the system clock. The time in remote
server is maintained properly. So that all machines can get the time
from that server.
Example:
$ rdate -p 192.168.1.5 -- Print the time returned by the remote
machine.
# rdate -s remote.pc.com -- Set the system time to the time returned
by the remote machine (Need Root permission).
# rdate -u myserver -- Use UDP instead of TCP as the transport.
# rdate -l myserver -- Use syslog to log errors and output (Useful
when it is used in cron jobs).
NOTE:
1) Remote server should run the time service in port 37.
2) Firewall should not block port 37.
Read : man rdate
HTH :)
