The timed options

The timed options support features such as time synchronization and scheduling, logging time changes to the console, and specifying the protocol used for time synchronization.

Timed option	Function	Function	Default value
enable	Enables time synchronization.	on off	on
log	Specifies whether time changes should be logged to the console.	on off	off
max_skew	Specifies the maximum allowable skew between the system time and the time server time. If the skew exceeds this value, synchronization does not occur.	`n`s `n`m `n`h	30m
proto	Specifies the protocol used to synchronize the time.	rtc (internal Real-Time Clock) rdate RFC 868 sntp RFC 2030 (preferred)	rtc
sched	Specifies the timed synchronization schedule.	hourly multihourly daily custom	1h (hourly)
servers	Specifies up to five time servers used by the timed daemon.	For example, `times1, times2.ntap.com, 10.15.46.92`	null string
window	Specifies a window of time around the synchronization time when the synchronization can occur.	`n`s `n`m	0s

For more detailed information on the timed options, see the na_options(1) man page.

Example clock synchronization

The following example configures timed to use the SNTP protocol with the default hourly synchronization schedule.
