It doesn't discuss it. According to the spec a timestamp with time zone is
a UTC value + a HH:MM offset from GMT. And intervals in the spec is either
a year-month value or a day-time value. One can only compare year-month
values with each other and day-time values with each other. So they avoid
the problem of the how many days is a month by not allowing it.
The spec is not a full solution, it's also not a useless solution. I'm
happy as long as the spec is a subset of what pg implements. If not then I
would like to be able to have both but with different names or something
similar (but I think that should not be needed).
