postgres UTC different from perl?

[Louis-David Mitterrand <vindex+lists-pgsql-general@xxxxxxxxxxx>]

Hi,

when trying: 

psql template1 -c "select  date_part('epoch',current_date at time zone 'UTC');"
date_part  
------------
1198015200

the result is different from 

perl -MDateTime -le 'print DateTime->today(time_zone => "UTC")->epoch;'
1198022400

Is there an issue with postgresql?
