I've found that running BOINC 4.45 causes the clocks on the three

The messing with the clocks which I have tied directly to the use of
BOINC 4.45 can really mess with some of the apps.

Roger,

this sounded interesting. Since I'm running this main machine with a
daily clock check from the official German Time Signal source in
Frankfurt I believe, this machine takes a daily check and adjusts the
clock to what it should be. In turn, this machine feeds my LAN with
NTP broadcasts so the other puters keep up.
Looking thru the logs since January 2003, I see no real differences in
where I didn't run Boinc, started with Boinc 4.13 and upgraded to
Boinc 4.45..... During this period the average daily drift has been
4.323 secs.... and apart from some odd values here and there I can
really see no big changes during that period.

Lordy!  I'm seeing 5 to 10 minutes a day with the occasional 3 to  5
hours over a couple of days.  Turn BOINC off and they keep time to WWV
with in seconds per week.

I did have an app that'd update the clocks, but it is no longer with
me for some reason.  I'm not sure what happened to it.

It could be an interaction between BOINC and some other app on the
computer.  Now that I think about it at one time I did have an app
that would argue with one of the earlier versions of BOINC.
Unfortunately, at least for now, I don't remember which one it was.
