I have no objections to adding a %T option, although deciding what 
format to use is a hassle. -1 for changing the default.

But let's look at the original request:

I've felt that pain too. You run a query, and it takes longer than I 
expected. How long did it actually take? Too bad I didn't enable \timing 
beforehand..

How about a new backslash command or psql variable to show how long the 
previous statement took? Something like:

postgres=# select <unexpectedly slow query>
  ?column?
----------
       123
(1 row)

postgres=# \time

Time: 14011.975 ms (00:14.012)

This would solve the "I forgot to time something" problem.
