GetSystemTime function (sysinfoapi.h)

Retrieves the current system date and time in Coordinated Universal Time (UTC) format.

To retrieve the current system date and time in local time, use the GetLocalTime function.

void GetSystemTime(
  [out] LPSYSTEMTIME lpSystemTime
);

[out] lpSystemTime

A pointer to a SYSTEMTIME structure to receive the current system date and time. The lpSystemTime parameter must not be NULL. Using NULL will result in an access violation.

None

To set the current system date and time, use the SetSystemTime function.

#include <windows.h>
#include <stdio.h>

void main()
{
    SYSTEMTIME st, lt;
    
    GetSystemTime(&st);
    GetLocalTime(&lt);
    
    printf("The system time is: %02d:%02d\n", st.wHour, st.wMinute);
    printf(" The local time is: %02d:%02d\n", lt.wHour, lt.wMinute);
}

// Sample output

The system time is: 19:34
 The local time is: 12:34
