Real-Time Clock Design

Base Real-Time Clock

The base Clock object provides an interface for the following operations. The base Clock does not implement the following operations.

1. Initializing the clock hardware
2. Resetting the clock (setting the reference time)
3. Getting the current real time
4. Spinning on the clock
   Spinning on the clock means to continually check the clock waiting for real-time to catch up to the desired simulation elapsed time.
5. Stopping the clock

Gettimeofday Clock

The GetTimeOfDayClock is a clock object that derives from the Base Real-Time Clock. The GetTimeOfDayClock uses system clock as the real-time clock.

The GetTimeOfDayClock implements the interface laid out by the base clock class

Initializing the Clock
