Re: remote clock sync

Hello,

> This works great!

I'm running ntpdate (xntp Package) which is much more accurate. ntpdate can
measure the time (especially if it is used with more NTP servers) more
exactly. It also not only sets the right clock, but in addition it adjusts
the system clock. Quoting the excelent man page:

       Time  adjustments  are made by ntpdate in one of two ways.
       If ntpdate determines your clock is off by more  than  0.5
       seconds it will simply step the time by calling settimeof-
       day(2).  If the error is less than 0.5  seconds,  however,
       it  will  by  default  slew the clock's time via a call to
       adjtime(2) with the offset.  The latter technique is  less
       disruptive and more accurate when the offset is small, and
       works quite well when ntpdate is run  by  cron  (8)  every
       hour  or  two.   

And my /etc/crontab entry:

57 *    * * *   root    /usr/sbin/ntpdate -t 20 -s host1 host2 host3
