Actually, it won't. When you first check out the project, there are
no DCU's so it really doesn't matter what the time stamps on the
source files are - everything is going to get compiled. on
subsequent updates, only the source files that get updated from the
repository will have changed time stamps, but that is exactly what
you want. Suppose person A and person B both check out a source code
file.
Person A modifies the file compiles it and commits it.
Then person B compiles the file.
Person B updates the working copy bringing person A's changes in.
Under the current scheme if person B does a compilation now, the
newer time stamp from the update will be noticed and the source file
compiled. If the source file date is set to the time when person A
changed it, or even committed it, nothing will happen when person B
compiles it. Even worse, on a large project with many source files,
person B may not notice that the updated file has been skipped.
If you've put the DCU's into Subversion, I strongly recommend you
take them out again. It's possible that they would change every time
you do a compile (if they contain a time stamp, for instance) even if
you don't change the source which generates unnecessary revisions.
Furthermore, you'd have to enforce a strict "make sure you compile
just before you commit" rule on your developers in order to make sure
that the compiled code was generated from the source code in the same
revision.
All the above is not to say that there aren't situations where
preserving the modification time of a file is not a useful thing to
have (just check back through the archives of the list, the feature
has been discussed at length many times), but managing source code
that will be compiled is not one of them.
