The Wisdom of Time

Hi,

what is the wisdom behind representing a TimeDiff as a struct of year,
month, week and so on, instead of simply the (fractional) number of
seconds, or similar?

In particular, the derivation of Eq seems to me to imply that sixty minutes
is not the same as one hour.

I haven't gotten around to play much with the module yet, but at least

  Prelude> (Time.TimeDiff 0 0 0 1 0 0 0) == (Time.TimeDiff 0 0 0 0 60 0 0)
  False

Could somebody please enlighten me on this issue?
