Measuring load/performance

That was back in 2017 or 2018 if I recall.....

No need for a beer....

Already sent one your way

Thanks!

for the sake of performance calculations are only performed when onUpdate - upon invocation (every 1sec) - detects one or more of the following:

- location is available for first time since startup; in this case both sunset/sunrise are calculated

- either lat/long changed by more than 1-degree (compared to what is cached in the View-class from last successful retrieval from Toybox.Activity.getActivityInfo().currentLocation); in this case both sunset/sunrise are calculated (1-degree is about 4-5 min diff in sunrise/sunset times)

- either already-computed sunrise/sunset 'becomes past' (i.e. current time 'moved on' such that it is > sunrise or sunset); in this case only the 'past' one is re-calculated

still one could argue these sunrise/sunset calculations are a lot of heavy lifting for a poor wristwatch CPU built and designed for low battery consumption, and which is typically expected to simply/for the most part only perform drawing.

not to mention even when all conditions above are false there is calc work involved just to determine that (every 1sec: get cur coords and compare to cached + compare cur date/time to cur sunrise/sunset)
