Just because Everyone Is Here In The Future, doesn’t mean you should be too!

The culprit, in camping’s reloader:

86  # The timestamp of the most recently modified app dependency.
87  def mtime
88    ((@requires || []) + [@script]).map do |fname|
89      fname = fname.gsub(/^#{Regexp::quote File.dirname(@script)}//, '')
90      begin
91        File.mtime(File.join(File.dirname(@script), fname))
92        rescue Errno::ENOENT
93        remove_app
94        @mtime
95      end
96    end.max
97  end

If your most recent modified time is more recent than your current system time, your reloader will break until you go Back To The Future.

I figure this is probably a rare case, and not really a bug, but if you’re playing around with system time dependant apps (I am), this might bite you.
