Sorry, this makes no sense. The whole idea of the last modified
timestamp is that it represents the time when this file was
last modified.
A lot of software is based on that convention, not only make.
Therefore, also svn should (at least in its default configuration)
follow that convention and touch the timestamp if it modifies
a file for example by svn update.
This is the only correct behavior (not disputing that other behaviors
may be useful as workaround in untypical situations).

Btw, for build systems of larger software, checksums are no option
because they are far too slow. Thats the reason why for example
also scons can use timestamps.
