Thanks a lot to both of you, corona688 and yoda.
Now it works fine, but when i try to change my time in the searchpattern, i.e. from 06-11
[ to take the data in between 06:00 - 12:00 ] i struggle again!
Can you please give me one more helping hand?

Thanks

       ager.  It uses any 64x64 pixmap as a background.

       dash.  A summary of options is included below.

       -B PIXMAP, --background=PIXMAP
	      Use the given pixmap as the clock background (size must be 64x64).
