Hi Gerd

No its not expected. In fact it appears to happen even for max-jobs=1 
when you compile the same file twice on the same run. I will try to 
track that down too.

If you look in ImgHeader.createHeader() and CommonHeader.writeHeader()
there are calls to write the timestamp, you can replace the date with
a constant eg new Date(1325107646).
