Well, as long as the number of seconds the value represents is small,
this indeed is a good argument for using dec. However, already
when we get into the hour range we're talking about 12-digit values
without any separators, and at least for me this means counting
from either end to find a place where to put a mental separator. So
if staying with dec, perhaps we should make these second based,
i.e. <ssss>.<nnnnnnnnn>?
