And someone could hand-edit the revision number...
I think we have to assume non-maliciousness, otherwise it's all
pointless.

As it is the build date I see nothing misleading about that at all.
I would buy the argument though that having the build date at all
is useless and should be removed.

Then it's not the build date.
If we want a last-changed-date we should change it to
that.
But having a build date that in Debian actually is the
last-source-change date, except when something goes
wrong and it's something completely wrong seems to me
to defeat the purpose (assuming there is one in the first place).
I vote for just removing the build date.
As an alternative I vote to change it to use the date of
the last commit if the source tree is clean and has git info
available, current date otherwise.
What do others think?
