Greetings;
I am creating a Qt application that depends on system clock (get the
current system time/date) to do time-dependent calculations. (calculate
duration from current time to a specifed/calculated duration in the
future, and set a QTimer's interval to that duration).
But the problem that can face me is the case when the user changes his
clock settings (i.e adjust phone's time to a different time). in this
case, the timer that has been set to some fixed duration can go wrong.
One solution i figured is to check for system time change every fixed
period (say a minute). But it seems a very ugly one since it is bad for
performance and not handy (wait for the next minute to come to check for
the clock and realize it was changed)
my question is: is there any way to get notified by the system clock of
any change/adjustments ? any signals sent by the system phone or
something like that ?
thanx in advance
