I believe that -05:17:32 is the offset of your local time zone as
compared with UTC. For example:
rhaas=# select now(); now
------------------------------2011-11-24 13:46:46.68016+00
(1 row)
rhaas=# set time zone 'Australia/Eucla';
SET
rhaas=# select now(); now
----------------------------------2011-11-24 22:31:55.792565+08:45
(1 row)
rhaas=# set time zone 'UTC';
SET
rhaas=# select now(); now
-------------------------------2011-11-24 13:46:58.480484+00
(1 row)
On my system, all current time zone offsets are multiples of 15
minutes, but historically that wasn't the case. It seems that in your
local time zone, the offset versus UTC was, as of January 1, 1894,
minus five hours, seventeen minutes, and 32 seconds.
