timestamp (military) at time zone without the suffix

Hi:

I would like to get the utc timestamp, 24-hr clock (military time), without
the time zone suffix.

Below commands were run nearly at the same time...

sqfdev=> select now()::timestamp(0) ;
now
---------------------
2018-07-11 15:27:12
(1 row)

...then immediately...

sqfdev=> select now()::timestamp(0) at time zone 'utc' ;
timezone
------------------------
2018-07-11 11:27:12-04
(1 row)

15:27:12 makes sense (it's a bout 3:30 in the afternoon EST).
11:27:12 doesn't make sense. UTC is 5 hours ahead. I would have expected
either 20:27 (if it stuck to military time, which I want), or 08:27 (P.M.,
non-military time)

And I want to get rid of the -04 suffix.

Is there a way to do this ?

Thanks !
