The computing apparatus running the program might not always be on.
"Always" is a reference to real time. So when it's turned off,
a duration object in the program would incur lost time.
So, some form of persistent storage is needed. I'd use values of types
that allow computing offsets in time. Store these every now and then,
e.g., as representing time passed.
