Yes, the relative timestamps of files matter when building from
source.  There are quite a few files which are generated by tools
which are not intended to be required to build from a tarball, such as
Bison and Autogen.  The tarballs' timestamps are carefully arranged so
the makefiles will not attempt to build those generated files, because
their timestamps are newer than the files they are built from.

Your best bet is to ensure you have Automake 1.10 or newer and
Autoconf 2.65 or newer installed, then use the ./bootstrap script to
reset the timestamps before committing to version control.  With a
little luck, then, those timestamps will be correct in a fresh
checkout, and if not, use ./bootstrap again.

FYI this might be better suited to hackers at lists.ntp.org.
