ntpwait - wait for ntpd to stabilize the system clock

       The ntpwait program blocks until ntpd is in synchronized state. This can be useful at boot time, to delay
       the boot sequence until after "ntpd -g" has set the time.

       ntpwait will send at most number queries to ntpd(8), sleeping for secs seconds after each status return
       that says ntpd(8) has not yet produced a synchronized and stable system clock.

       ntpwait will do this quietly, unless the -v flag is provided.

       One of the following exit values will be returned:

       0
           Successful program execution.

       1
           The operation failed or the command syntax was not valid.

       2
           Operation was interrupted by signal.

       -n number, --tries=number
           Number of times to check ntpd. This option takes an integer number as its argument. The default
           number for this option is: 100.

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

       -s secs-between-tries, --sleep=secs-between-tries
           How long to sleep between tries. This option takes an integer number as its argument. The default
           secs-between-tries for this option is: 6.

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

       -v, --verbose
           Be verbose.

           By default, ntpwait is silent. With this option, ntpwait will provide status information, including
           time to synchronization in seconds.

       -V, --version
           Print the version string and exit.
