ntp gives up completely if your clock is too far off. You should set your clock so it is as close as you can get it. Is your clock 5 seconds slow or fast? No problem. Is your clock 1001 seconds(or more) too slow or too fast? Forget ntp... it will not even try to sync the clock.

ntp needs to figure out how bad your clock is. If you reboot a lot, it has to keep starting from zero. With a drift file, it writes the drift into the file. Later when ntp restarts, it rereads the drift file. So it doesn't need to start completely over.

What server are you using? Post your whole ntp config file.

adjtimexconfig

ADJTIMEXCONFIG(8)					      System Manager's Manual						 ADJTIMEXCONFIG(8)

NAME

       adjtimexconfig - find kernel clock variables and save for reboots

SYNOPSIS

       /sbin/adjtimexconfig

DESCRIPTION

       This script uses adjtimex(8) to find values for the kernel variables tick and frequency that will make the system clock approximately agree
       with the CMOS clock.  It then saves these values in the configuration file /etc/default/adjtimex so the settings will be restored on every
       boot, when /etc/init.d/adjtimex runs.

       adjtimexconfig uses the drift rate recorded in /etc/adjtime to adjust the times it reads from the CMOS clock.  If you find the CMOS clock
       has a systematic drift, read the clock(8) or hwclock(8) manual page, modify /etc/adjtime as required, and run adjtimexconfig again.
