Feature Request

Many locales have the bare minimum when it comes to test cases. While I understand it can be tedious and repetitive to write out test cases that appear the same for multiple timeframe units, I still believe we should make it necessary. If we do ever make changes to any locale files, which seems to be more often as of late, we want to ensure we aren't being mislead by passing test cases, when there could potentially be some underlying bug/edge case (so often the case with locales) that we'd be missing.
