[KimDaBa] Remove time info from images

[Eugen Dedu]

Hi,

How can I remove time (not date !) information from images?

I inserted images taken with my old camera and kimdaba automatically 
uses the file last modification time.  I can select images and correct 
the date, but how can I remove the time (as I do not know it precisely)? 
  (I found that it's -1 in the index.xml file, but I would like to do it 
from kimdaba.)

Cheers,
