Enable IndexActionTests and WatcherIndexingListenerTests Backport #38738

fix tests to use clock in milliseconds precision in watcher code
make sure the date comparison in string format is using same formatters
some of the code was modified in #38514 possibly because of merge conflicts

closes #38581
Backport #38738
