Say that I am a client that wants to synchronize my time with a
server's time. So I send a time request and receive a time
response from the server. If this takes too long time (say, more
than a second), the time is not set because it will be
inaccurate. Otherwise, I call "SetSystemTime".
The code would look something like:
A := GetTickCount;
SendTimeRequest;
NewTime := WaitForTimeReply;
if GetTickCount-A < 1000 then
SetSystemTime(NewTime);
However, there is a small chance that between the GetTickCount
and the SetSystemTime calls, Windows will decide that it's time to
do a disk cache flush, refresh a web page, or whatever. And as a result, the
computer's clock will be wrong.
Is there a "bulletproof" way of avoiding this behavior, or
another way to design, etc?
