It's supposed to look very spreadsheet-like, so I can't compress like
that.

It's a neat technique, though. I did work on a front-end for an mp3
repository, and I converted the sum of seconds to get the number of
days of continuous audio on the server. At the peak we had over 50
days of mus^H^H^Hsound on the beast. So, from your method:

def convertseconds(ticks):
    suffixes = [ ('seconds', 60.0), ('minutes', 60.0), ('hours', 24.0), \
                 ('days', 365.24), ('years', 1) ]
    for suf, quant in suffixes:
        if ticks / quant < 1.0:
            break
        ticks /= quant
    return '%.2f %s' % (ticks, suf)

Wow, that's cool. Much better than the way I did it last time. Test
results were plausible. (I could double check, but, well... :^)
