(Out of curiosity: what actually *needs* real timestamps?:
- They're generally useful to people, of course; ("what did I
change last tuesday?")
- Make uses them, though in theory perhaps it could do the same
job by caching records like "object X was built from
versions a, b, and c of objects A, B, and C respectively".
But a lot of uses are probably just to answer the question "did this
file change since the last time I looked at it"?
Of course, however theoretically useful, there's always the argument
that linux-specific interfaces are unlikely to be used by anyone except
Lennart Poettering.)
