ntp-wait - Wait for ntpd to stabilize the system clock


ntp-wait [-flags] [-flag [value]] [--option-name[[=| ]value]]

All arguments must be options.


ntp-wait will send at most num-tries queries to ntpd(8), sleeping for secs-between-tries after each status return that says ntpd(8) has not yet produced a synchronized and stable system clock.

ntp-wait will do this quietly, unless the -v flag is provided. This can be useful at boot time, to delay the boot sequence until after ntpd -g has set the time.


Number of times to check ntpd. This option takes an integer number as its argument. The default number for this option is:

The maximum number of times we will check ntpd to see if
it has been able to synchronize and stabilize the system clock.

How long to sleep between tries. This option takes an integer number as its argument. The default secs-between-tries for this option is:

We will sleep for secs-between-tries after each query
of ntpd that returns "the time is not yet stable".

Be verbose.

By default, ntp-wait is silent.
With this option, ntp-wait will provide status information.
