Re: Hidden timeskew problems might show up on 2.6.x kernels
This is a well-know problem: See
<< The problem with timestamp skews and Debian source packages>>
in the autotools-dev.
One of the simplest solution is to add
AM_MAINTAINER_MODE in the configure.ac file
so that make will not run automake/autoconf.
Also some buildd are really slow and you should not assume they
will perform the patching in 1 second.
Imagine a large red swirl here.
