Change system date on Windows using Qt

Question

Hi,

What is the most appropriate method to change the system date (on Windows) programmatically using Qt4. I'm using Qt Creator 1.3.1.

Answer 1

Use Windows API, GetLocalTime and SetLocalTime.

SYSTEMTIME localTime;
GetLocalTime(&localTime);

localTime.wHour = 21;
localTime.wMinute = 30;

if (SetLocalTime(&localTime) != 0)
{
    // ok
}
else
{
    // failed
}
