Just as an FYI, if you want to reassure yourself that the ORDER BY
is being applied as intended, you could do the following:

(
 select 1 as hint, start_time as when [...]
 union all
 select 2 as hint, end_time as when [...]
) order by seq, when

This is ANSI/ISO standard, and works in PostgreSQL (based on
a quick test).

hmm, try pushing the union into a subquery...this is better style
because it's kind of ambiguous if the ordering will apply before/after
the union.

select q.when from
(
 select 1 as hint, start_time as when [...]
 union all
 select 2 as hint, end_time as when [...]
) q order by q.seq, when
