SUM: Strange Time-problem

thanks to all who replied!
You're right, it had to do something with an NFS-mounted system, but a
time-sync was not the only problem:
I've figured out what was wrong, it was more a problem of our SCM-Tool.
We're using a SCM-System (Rational ClearCase), and this program stores some
data on a NFS-Filesystem. Now, the following scenerio can occur:
The buildhost starts making a binary, and sends a request to the
ClearCase-Server to write the data. The Server replies, and starts a
background task to write the data.
(The writing, of course, takes a little time, 1/2 - 1 second, so this is the
timestamp of the binary) And now, make gets confused: The next time it tries
to access the file, the file is newer as expected, so make warns abt.
clock-skewing...
Funny behaviour, especially this occurs also when the two servers _are_
synchronized!
So, this behaviour is more a problem of ClearCase, :-))
