NAME
rdate – set the system's date from a remote host
SYNOPSIS
rdate [-46anpsv] host
DESCRIPTION
rdate displays and sets the local date and time from the host name or address given as the argument. The time source is an RFC 5905 protocol SNTP/NTP server.
The options are as follows:
- -4
-
Forces rdate to use IPv4 addresses only.
- -6
-
Forces rdate to use IPv6 addresses only.
- -a
-
Use the adjtime(2) call to gradually skew the local time to the remote time rather than just hopping.
- -n
-
Use SNTP (RFC 5905). This is the default. This protocol counts 32 bits of seconds from January 1, 1900 and will handle rollover to a new NTP era in February 2036.
- -p
-
Do not set, just print the remote time.
- -s
-
Do not print the time.
- -v
-
Verbose output. Always show the adjustment.
