Version Bump in Gemfile.lock
Add specs to double-check that the absolute strategy works properly with nil dates
Whitespace
Absolute timeframe checks should not care about time zones
Rework the instance #in_progress? method so that it reused logic from #started? and #ended?
Remove non-scoping in_progress methods which I added for a reason but can't remember

All specs pass without them.
