So, do we conclude that Microsoft's "Embrace, extend, and
extinguish" strategy now applies to Time itself?<br>

Just to let you know....<br>
<br>
In search of a problem completely unrelated to fpc and Lazarus I
found out that the reason of the severe timing inaccuracy making
this application being absolutely unusable for the desired task,
has been Microsoft <big>"</big>Active Directory". <br>
<br>
After I installed Automachron, syncing the PC with an "official"
NTP Server, the problem vanished. (But the IT department told me
that this PC will see severe issues, e.g. Active Directory
preventing user login. )<br>
<br>
I seem to remember, that many FPC built Projects either directly
use the PC clock as a source for timing or use EPIKTIMER that in
some incarnations use a CPU based hardware timer and in other
incarnation, use the PC clock as well. <br>
<br>
Now I found that with "Active Directory" in my installation the
PC clock erratically fluctuates at rates of at least some 40
seconds per hour and at least for a total amount of 40 Seconds. <br>
<br>
So it is a lot worse than the uninfluenced clock of even a really
cheap PC and unusable for many timing tasks. <br>
