date-time problem

[aegis]

hello to everyone,

i have the followign problem:

i need to get the system date-time {i think it is done like this--> QDate myDate(QDate::currentDate())} and then i

need a way to add minutes(!!) to this variable....

in particular i want to make a program{actually part of a another program} that will print on a label dates&times.

The problem is that i must print the date-time every hour.But also simulate an hour with 1 minute{i believe that i can do so with the Sleep() function}...

so a possible output could be:
Wed Feb 11 2007 22:09
Wed Feb 11 2007 23:09
Wed Feb 11 2007 00:09
Wed Feb 12 2007 01:09
....
....

thanks for your help

PS:: sorry for my english...

Is that a GUI application? You don't want to sleep() in a GUI application because that would freeze the whole application by blocking the applications event loop. You can use QTimer to perform periodic tasks.

i forgot to say that i am rather new to gui designs...yes it is for gui application.In theory at least i am thinking of a button that when pressed the whole application would stop until the dates are outputed to a file or label....but the problem isn't there.

The problem is that i dont know what type to use to represent date and time so that i can have the ability to add minutes to an original time....

Take a look at QDateTime. It represents both date and time. It's basically a combination of QDate and QTime.

QDateTime dateTime = QDateTime::currentDateTime(); // get current date and time
dateTime.addSecs(60); // add minute
QString str = dateTime.toString(); // the date time as a textual representation

QDateTime dateTime = QDateTime::currentDateTime(); // get current date and time
dateTime.addSecs(60); // add minute
QString str = dateTime.toString(); // the date time as a textual representation
