DiffTime in Data.Time

I'm trying to use Data.Time, and I'm totally confused. DiffTime is
abstract, and I don't see anything that maps into it. How do I
construct one? I would like to then use the result to create a value
of type UTCTime, but it seems (currently) like this might be easier.

Thanks,

It's an instance of Num etc. (as seconds).

Re: DiffTime in Data.Time

Ok, that's much simpler than I was making it. fromIntegral or
fromRational does the trick. Obvious in hindsight, I guess. Thanks!
