I'm sure somebody as experienced as Fredrik doesn't need to be told why
peppering code with magic constants like 84600 are a less than ideal
solution -- and for those who do need to be told, carefully compare what I
wrote to what Fredrik wrote to see one of those reasons.
Arguably a better solution would be to do this:
seconds = td.days * 24*60*60 + td.seconds
Still not ideal though, although that depends on just how often you need
to convert days to or from seconds.
