You mean the -G option which was added in recent ntp versions? The -g
option just temporarily disables the panic threshold and should't make
a difference (unless the initial offset is larger than 1000 seconds).

With older ntp versions it's recommended to run ntpdate -b before
starting ntpd in order to speed up the initial synchronization.
