Name
rdate - network date client
Syntax
/etc/rdate [ -s ] [ -v ] [ network ]
Description
The command is invoked at boot time to reset the system date and time to the current network date and time. The program sends a broadcast
datagram packet on the specified network or on the system default network if no network is specified. The program will then wait two sec-
onds for responses. After that time, the arithmetic median of the responses is taken.
Options
-s The system date and time will be set to the median value.
-v The time values returned by all responding hosts will be reported.
Restrictions
In order for to determine a network time, at least one of the running hosts on the network must be running the internet time service.
Machines with their own battery-backed-up time-of-day clock may not desire to set time in this manner.
