It doesn't really matter, since the table is used only internally, and
only holds current accepted values for time zone offsets. The current
scheme works.
It might be useful to change the units, but how they are stored is an
internal detail without much importance. Someone at some point decided
that minimizing row width and table size was important (probably back in
1989 ;) and the table is structured with that in mind.
