There's no difference, as you can't do time-accounting non-strict and
still expect it to give meaningful results: I'm merely trying to be
helpful. None of the other solutions allow for the IO Monad.
Firstly, I'd phrase that differently -- the IO Monad doesn't allow for
the other solutions -- the other solutions are the truly functional
ones. Secondly, I'm curious as to why you think that the two are
incompatible, are you saying that for any meaningful kind of
computation we need to resort to IORefs? I'd strongly contest that
idea.
