in thread Time Drift when using Win32::Daemon::Simple

Not sure I follow (been a long couple of days). Do you mean replace the daemon's interval call back with this timing loop? I ran a simple test and it does seem to stay accurate to the second.

The other approach I had considered was to test for how much the timer had drifted at safe periods, then pause and resume the service to get back on synch. It doesn't elimate the problem, but allows me to specify where it skips ahead to the next minute. This would eliminate the risk of my missing a significant time period.

    1. Yes. Just replace the

    ServiceLoop(\&callback);

    with the loop.

    2. I don't think I follow, you mean that your callback would wait 59 seconds in case the time drifted to put it back in sync? Well you can do that. Apart from the fact that you will not be able to stop the service (via the Service Manager) during those 59 seconds you are safe.
