bugfix: make stopwatch and divetime run in sync And this shows the fundamental issue in the difference between dive time and stopwatch time. The dive time is constructed on the RTE, and rather independently, the stopwatch time is constructed on CPU1. This works rather well, but not perfect. This commit fixes things in a relatively straightforward way. Instead of incrementing the stopwatch locally on CPU1, simply use the same time data that is coming from the RTE. Some logic was added to make this stopwatch resettable again. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
