Hello everybody!
I am using a debian (testing) linux on a virtual machine of VMWare (in a
linux host).
I found, that the time in the VM was awfully wrong and hoped to fix this
with ntp.
Unftorunately this was not the case. I started ntpd and the time was set
properly. After about 5 hours the time deviation was more than 5 minutes.
The strange thing: ntpq tells me, that ntp is absolutely aware of the
deviation (first the deviation is small, but it is growing bigger and
bigger), but it fails in synchronizing correctly. Why?
This is a snippet of my console at 16:15:00

And now my questions are:
1. Why fails ntp in synchronizing, although it is aware of the deviation?
2. I assume this problem has to do with the fact, that all this is running
in a VM (virtual machine). Has anybody an idea how to improve the situation?
Thanks!
