how to get the current system time ?

[Petr_Kropotkin]

Using standard C++ functions how can i get the current time from my system since noon?

I tried:

time_t hours;
hours= time(&hours);
last_time=hours-12;

time_t hours;
hours= time(&hours);
last_time=hours-12;

To copy to clipboard, switch view to plain text mode 

This won't work.

Why dont you use ?
QTime::currentTime();

[Petr_Kropotkin]

That makes it too easy. The idea is not to use it.

[aamer4yu]

last_time=hours-12;

Had you provided the necessary overloaded functions ? (-) and mechanism to create object out of numeric value...

You want "not easy":

• Add a camera pointing at a clock, take a picture of the clock, interpret the graphic image as a time.
• Create a temporary file, take the time from the file.
• Get the time from a time server
