# 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
|
|
1. Resetting the clock (setting the reference time)
|
|
1. Getting the current real time
|
|
1. Spinning on the clock<br>
|
|
Spinning on the clock means to continually check the clock waiting for real-time to
|
|
catch up to the desired simulation elapsed time.
|
|
1. 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

### Resetting the Clock (setting the reference time)
|
|
|
|

|
### Getting the Current Real Time
|
|
|
|
