# Specifying -g on the command line allows ntpd to make large adjustments to
# the clock on boot.  However, if Restart=yes is set, a malicious (or broken)
# server could send the incorrect time, trip the panic threshold, and when
# ntpd restarts, serve it the incorrect time (which would be accepted).
