timer callback greater than 2 power 31

Hi,

I think that you can use a QTimer to fire up to 49 days:
The QTimer needs miliseconds

2^32 = 4294967296 maximum miliseconds
4294967296 / 1000 = 4294967,296 seconds
4294967 / 60 = 71582,7882 minutes
71582,7882 / 60 = 1193,04 hours
1193,04 / 24 = 49,7 days

It is not enough you can also fire the timer every day and when it's fired you can use a counter to check if "days" have been passed.

Hi,

Yes you are correct but I was looking timer event callback for specific date, like for example a reminder or an anniversary notification to be popped up. Actually I need it because
the Qtimer::start(int) is limited on s60 as the internal timer class takes int microseconds as input so you cannot feed maximum of int in the start as what ever is fed is multiplied 1000 to make it to microseconds

for example you want 32 seconds you feed
QTimer::start(32*1000);

internally it becomes
32*1000*1000.

now if you feed max of integer which is 2 ^ 31 = 2147483648;

internally it become 2147483648*1000 signed integer overflows.

So I need a different mechanism where I could request the timer server give me a callback at the specific time, so that I could avoid this problem.

Hi,

Create a timer fired every second and compare dates there.
