SYNOPSIS
       ntpdate-debian  [-bBdoqsuv]  [-a  key]  [-e authdelay] [-k keyfile] [-o

DESCRIPTION
       ntpdate-debian is identical to ntpdate(8) except that it uses the  con-
       figuration  in /etc/default/ntpdate by default.  ntpdate sets the local
       date and time by polling Network Time Protocol (NTP) servers.
