timer callback greater than 2 power 31

[sriky27]

Hi,

How to request a callback greater than the maximum limit of int datatype, is it possible to get a callback at a given time, for example
QDateTime dateTime;
dateTime = dateTime.toLocalTime ();
dateTime.addDays(31);

Now I want to request a callback at set dateTime i.e after 31 days. Is there any api. Please advise.
