Earlier today, I saw on Lemmy that comments made within the last hour since DST were now in the negatives since time had rolled back. If a database uses time like this for search operations, would that interfere with them? Could it corrupt the database?
Until they decide to reverse it, or until they make a different change.
Just use Epoch time for backend and calculations, and use local time for displaying to the user (or UTC for debugging systems that span time zones)
