NAME
ntp-wait - wait for NTP server to synchronize
SYNOPSIS
ntp-wait [ -f ] [ -n tries ] [ -s sleep ] [ -v ]

OPTIONS
-f Force hard failure if state is unknown. -n tries Number of tries before giving up (default 1000 = 10min+) -s sleep Seconds to sleep between tries (default 6s = 10/min) -v Be verbose.
