version1 uses a fixed 100 columns output, version2 a fixed 80 columns output.
Why do you force it to be 80 chars wide? How about simply limiting it to 80 chars?

The whitespace after the time seems totally unnecessary. Sure, it's in line with the version where you display the total percentage, but a user is never going to see both at once so why bother? Just get rid of the whitespace and either use a fixed length for the progress bar or start after the time and fill it up to 80. I'm in favour of pinning the length to 20 chars though because I feel like this gives enough visual indication of progress. This will result in the progress bar being at different positions all the time, but if the user only ever sees one this does not matter. Apart from that I like the idea. I don't see any value in having the output cluttered with 100% progress bars.
