I think, 'ntp' is a better way to solve this...

But this will remove information about the age of (packaged) files,
won't it?  E.g. previously, I was able to see on the target machine,
when a file was modified. It is not a critical feature but often very
useful.

Now, the date on image will be either the former date or the date when
the staged tarball will be extracted (--> e.g. after 'bitbake -c clean').
Sounds confusing.
