Hello all!
I installed Meinberg's build of ntpd for Windows:
ntpd 4.2.4p8@lennon-o Dec 09 10:46:55 (UTC+01:00) 2009 (3)
While it initially synchronized successfully, it didn't work for two days. Now
I'm more than 60 seconds behind.
Connection to the closest remote NTP server works fine, see

They are no longer required and when you are mobile you should
not have them. The pool.ntp.org dns determines where you send
your request from and returns servers that are local to you.
Thanks for the suggestion, Rob. Implemented.

It's a matter of opinion now,
I think if the servers are under your control and supervision two is
enough to provide pretty good availability and three might not have as
much bang per buck. But if you don't control the servers then you
don't know if any of them are correct so I'd want enough so
