rdate − get the date and time via the network
rdate [−p] [−s] [host...]
Rdate uses TCP to retrieve the current time of another machine using using the protocol described in RFC 868. The time for each system is returned in ctime(3) format. The following is an example:
|
% rdate uci mc |
[uci] Sun Mar 24 20:35:41 1985
[mc] Sun Mar 24 20:36:19 1985
OPTIONS
|
−p |
Print the time retrieved from the remote machines. This is the default mode. | ||
|
−s |
Set the local system time from the time retrieved from the remote machine. This, quite naturally, is only effective for root. |
/etc/services map service name to socket number

/etc/hosts |
