Unix Time Updates.

This removes the `time` trigger from `UnixTime` as requested in #607.  It also updares the output to show the epoch as used and the time which results which is vaguely more useful.
@moollaza I don't really know how the font-family stuff works (i.e. I stole this line from somewhere else at some point.) It might be that this _is_ the font-stack?

Regardless, won't this fall back to `monospace` when the others are missing?
