timestamp cast to abstime problem

Does anyone know why this returns 0 and not 3600?

test=> select '1970-01-01 01:00:00'::timestamp::abstime::int4;
int4
------
0
(1 row)

My time(2) manual page says:

The time() function returns the value of time in seconds since 0
hours, 0 minutes, 0 seconds, January 1, 1970, Coordinated Universal Time.

Also, why does my TimeZone show as Poland?

test=> SHOW TimeZone;
TimeZone
----------
Poland
