The timer is just the difference between the timestamp when the timer was started and the current timestamp, but I don't know of any timer app that let's you import/export timestamps as easy as that would be to implement.
This timer allows pausing though, so I think you have to store a sequence of timestamps
Does it show the "laps" and their times? If not, I think it can still be implemented by storing just two values - time delta before previous stop and timestamp of previous start/un pause.
It does, those can be a list of timestamps with a lap flag. Pauses can be a pause/resume flag.
Fairly easy data structure to build.
If you rooted the iPhone could you use some kind of hex editor?
Probably, the data exists somewhere
