Working on a group project, and I have been tasked with creating a time design 

• Clock system must be self-contained object that can be instantiated, and given start, pause, fast forward, and slow down settings.
• Clock must be able to trigger a specific action at a specified rate (x_times every y_units) The user sets x, the number of executions per Unit (seconds, minutes, hours, days)×
• Clock can set time to accelerate at various speeds (1x,2x,3x....)
• Create a clock
