Mailing processing ignores timezone, and sends mailings at wrong time

I have date.timezone set CET (for both CLI and FPM server)
Server time is correct.

when I schedule a mailing job to launch immediately, for instance at 10am, civicrm will send this mailing at 11am, and will write 10am in "completed at" in scheduled and completed mailings report.
I use wp-cli every two minutes to run jobs:

cd /home/www/wordpress && /home/www/bin/wp-cli --url=www.domain.pl --user=marcin civicrm api Job.execute auth=0

This seems to be a problem with running via cli, because manually launching the job from civicrm administration panel sends the mailings at the right time.
