java - Properties.store() - suppress timestamp comment

Question

Is it possible to force Properties not to add the date comment in front? I mean something like the first line here:

#Thu May 26 09:43:52 CEST 2011
main=pkg.ClientMain
args=myargs

I would like to get rid of it altogether. I need my config files to be diff-identical unless there is a meaningful change.

Guess not. This timestamp is printed in private method on Properties and there is no property to control that behaviour.

Only idea that comes to my mind: subclass Properties, overwrite store and copy/paste the content of the store0 method so that the date comment will not be printed.

Or - provide a custom BufferedWriter that prints all but the first line (which will fail if you add real comments, because custom comments are printed before the timestamp...)
