clock is complete wrong after installing ntp package

Package is right?
If i open up the help i get this page:
http://docs.xfce.org/xfce/xfce4-panel/clock

But ubuntu-bug says, there is no package "clock".
-------------------------------------------------------------------------

I did a fresh installation some days ago of 15.04 beta.

Yesterday (sunday) i change some things, and installed ntpdate for correct internet time and date.
The "Clock" as it is called in XFCE4-Panel was right and worked good AFTER the shift to summer time.

Now, today (monday) morning at 6:33 the clock was on 3:58 !!!
I double checked all things, it is still internet time.
