PDT stands for Pacific Daylight saving Time, which is used in states
like California, Oregon and Washington in the United States.  The fact
that date command prints the time in PDT means that you have not
updated your timezone information according to your area.

The standard procedure for this is

	rm /etc/localtime
	ln -s /usr/share/zoneinfo/your-timezone /etc/localtime

/usr/share/zoneinfo/Europe/Berlin might work for you?
