Inheritance provided UML diagram $($but not implementation$)$ for SimClock,

and most of the implementation $($but not UML$)$ for TZClock. you should finish both. Also, you should change the clocks to use equals $($and not equalTime$)$ and toString $($and not printClock$).$

Create a UML diagram showing for SimClock and TZClock. $($One more reminder: Don$$t use equalTime nor printTime$).$

Implement the two classes.

Write a program that demonstrates polymorphism and tests your class, including the possibility for incrementSeconds$()$ to produce changes to minute and hour.
