This is one reason I advocate a DB-based solution rather than an FS-based solution; after all, the FS solution *IS* simply using the FS as an ad-hoc and anemic database, and using the timestamp-field this way is essentially analogous to querying a 'time' column when what we *REALLY* want is a 'version' column (not "1.2.3" but more like "build # X").
A lot of problems with build-systems come from (a) using the FS as an ad-hoc DB, and (b) the differences in the FS like "/ vs \ vs :" directory separators, or case-insensitive vs case-sensitive.
