How to pause and start a timeline at the same point with specific key frames

Question

I need some help figuring out how to implement pause functionality into my program.

I'm am creating a timer that I want to be able to pause and play from the same point in time.

Expected outcome: After the pauseButton has been pressed, the startButton picks up right where the pause button left off and displays the same time.

Current outcome: After the pauseButton has been pressed, pressing the startButton starts the timer 2 units less than where the pause button left off. So if the time was paused at 10:58, the startButton picks up the time at 8:56.

Another issue I'm having is that after the pauseButton has been pressed, each iteration of the time change decrements the secondTime timeline by 2 instead of 1 and the minuteTime timeline never changes.

Any help is greatly appreciated. Thank you
