Follow-up:
My initial question was about oddly-formatted date/times. The suggested
solution of casting directly to timestamp with ::timestamp is not as
flexible as the to_timestamp function that I was trying to avoid. For
example, this fails because of the day-before-month format:
SELECT ('18.09.2015 18:01:40')::timestamp
--ERROR: date/time field value out of range
whereas this works, but results in a timestamp *with* time zone that makes
assumptions about daylight savings times:
SELECT to_timestamp('18.09.2015 18:01:40','DD.MM.YYYY HH24:MI:SS')
I ended up with this simple solution, which does what I wanted to and avoids
time zones:
SELECT (to_date('18.09.2015','DD.MM.YYYY') ||' '||'18:01:40')::timestamp
Adrian: thanks for your observation about wildlife-human interactions --
that is a useful reminder since I'll be looking at traffic patterns.
