I found an open issue on the react-native github which seems
related https://github.com/facebook/react-native/issues/31523
but after following all of their suggestions I still have the
same error. I tried:
- Removing @babel/plugin-proposal-class-properties & @babel/plugin-transform-flow-strip-types
- Adding @babel/plugin-transform-flow-strip-types
This kept displaying the wrong date/time for certain timezones.
So i'll just show the actual ISO date we store in the database.
Maybe later i'll figure out what was going on here or use a
date library (probably not).
This was supposed to solve the timer stopping sometimes
when the application was in the background.
It was actually stopping because of battery optimizations.
