WP-34S: Stopwatch - bug, feature, or user error?

[Brad Barton]

Would it be possible to set a flag if the stopwatch is running, and store the difference between stop watch value and the internal clock when the idle timer puts the machine to sleep? Then on wake up, check the flag and if it's set, restore the stopwatch value by adding that difference to the internal clock time, and keep the stopwatch running.

You'd only have to store 2 values: the difference in time, and the flag that says "stopwatch running". This would work even if the calculator is switched off, but I'm not sure how much persistent memory you have to work with.

Total noob here, so just wondering.
