Title: Error when other classes that extend Time call `now`

Ran into a problem where an OpenOffice parsing gem was failing with "no implicit conversion to float from nil". Tracked it down to a DOSTime class that extends Time that was failing due to interactions with time-warp.
Included is a small tweak to stop that happening, with a test.
