Better feedback for long running tasks

I have been writing some data loading software at the moment which involves gigs and gigs of data. It can take hours to load. I spent time writing a progress monitor to allow monitoring.

I realised that what was much better than just saying 4 hours to go (and not the cute microsoft minutes remaining estimation either) it's really good to say,

5 Hours, 21 minutes remaining, Estimated finish time 4:32 PM

Giving a clock time is so much more human friendly.
