NAME

  rdate	- network date client

SYNOPSIS

  /usr/sbin/rdate [-s] [-v] [network]

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.

DESCRIPTION

  The rdate command is invoked at boot time to reset the system	date and time
  to the current network date and time.	The rdate 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 seconds for
  responses.  After that time, the arithmetic median of	the responses is
  taken.

RESTRICTIONS

  In order for rdate 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.
