Your link doesn't work.
I have a parallel port clock lying about. I can't remember what it's called (there's a photo of it somewhere under my user account - might be on amiga.org), but IIRC it requires 2.04. I have no idea if it still works, but if it doesn't it's probably just the battery (again, no idea if these are easy to replace). The instructions and disk were with it last time I saw it.
If you want it I'll happily send it to you for cost of postage (I can send it as a 2-3 day small packet, air-mail for £8 (~$13) to Canada, although I'd need to weigh it to confirm that price)
edit It's just come to me - it's a TurboTech.
