for good practice and clean code I faced an inconvenienced because local time in my flutter app was changed unexpectedly. That was because initializeDatabase() function silently change _local to _UTC . using setLocalLocation() for that makes debugging easier

Clarified that package does not provide current timezone

Tweaks and anti-bug-ensurence.
