Hi, i am a beginner

I would like to know how to update the date and time of the Sytem using QT Classes.

I have come across QDate , QTime , QTimeEdit, QDateEdit and QDateTimeEdit Class but i dont find any option on updating date and time of the System.

My idea is if user wants to change the date and time he should and system should run from the user set time and date should get updated.
