time
time_t time (time_t *currentCalendarTime);
Purpose
Determines the current calendar time. The result is stored in the specified output variable and is also returned by the function. The value that is returned is the number of seconds since January 1, 1900 Coordinated Universal Time (UTC), formerly known as Greenwich Mean Time (GMT). You can pass this value to the localtime function to obtain the time for your time zone. You can then pass the structure pointer returned by localtime to either asctime or strftime to obtain an ASCII string representation of the time. time returns -1 if the current calendar time is not available.
