Question:
When I create the TTimer component, it does not fire at the
correct specified time. How can I get more accurate results?
Answer:
Windows timer event were not designed to accommodate
hi-resolution timing. In other words, while you may set the
timer to fire every 1000 milliseconds, it may fire sometimes
at intervals longer than 1000 milliseconds. Values below 55
milliseconds will never fire on time under Windows, since this
is the Timer components minimum resolution. You can get the
time during the timer event and compare it to the last time
the event fired to receive a better timing resolution.
