Question

Is It possible to increment or decrement the system time ? If so, Please give your thoughts.

During my search, I can able to get the current system time and increment or decrement the time using SYSTEMTIME structure.

EDIT

In Linux, gettimeofday() function to get the current system time and settimeofday() function to set the system time given by the user.

Similarly, I need those two similar functions in Windows.

Answer 1

I found out the answer for my question.

We can able to increment/decrement the system time in windows.

GetSystemTime() and SetSystemTime() functions are used to get the current system time and set the system time by the user.

SAMPLE

 SYSTEMTIME st;
 ::GetSystemTime(&st);
 st.wHour += 1;
 ::SetSystemTime(&st);
