My servers all run in UTC, so that query works here.
The first query where I noticed this, I had just run date +%s and used
that value in now() - 1427998368::reltime, like:
One term:
:; date +%s
1427998617
Other term:
cloos=# select now() - 1427998617::reltime;
?column?
-------------------------------
1970-01-01 06:00:03.137866+00
(As you can see it took me 3 seconds to do the copy-paste...:)
For now()-'epoch' I get the format:
16527 days 18:27:01.688195
but for 1427999266::reltime I get:
45 years 3 mons 1 day 12:27:46
I wonder whether the YMD to D conversion takes into account the actual
number of Bissextile years?
If so, I guess that is another nail in reltime's coffin.
now() - to_timestamp(1427999266) worked correctly, but that is not
unexpected given to_timestamp's definition.
