As a general rule, delay measurements should be done with the monotonic clock, not the wall clock (the real-time clock). As far as I know, Qt timers already do so internally. But of course, your own code should never request and use the wall clock for time measurements. > One solution i figured is to check for system time change every fixed > period (say a minute).

That is not something you should be concerned with in the first place. If you do, it is a very strong hint that you are using the wrong clock. _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
