Try "today".

I don't know about every change.  What I do know is that's it's very
difficult to parse time and date in every possible combination.  Order
is important ("today 12:00" vs. "12:00 today") and some numbers could
be interpreted in more than one way.

If you can create an algorithm that works in every case, let us (the
list) know and I'm sure somebody will code it.
