searching for a big clock

[Al Bogner]

I am searching for a _big_ digital clock including seconds for my
XFCE-desktop, which is _not_ in the panel. The reason is the following:

I want to take a simple photo of the screen with my camera, that is why,
the bigger the better. Then I compare the exif-time of the image with
the time I _see_ in the photo. Afterwards I correct the time difference
in the EXIF-metadata with exiftool to get correct gps-values.
