Again, that depends on what's the intent behind placing the date into
release tag.  From Toshio's mail I know what's the rationale behind
using the date, so I can agree with you at this point.

Currently, you have to bump "base" release tag in addition to changing
the date portion.

Yes, snapshot packages should, under the naming guideline, contain the
date and the string "cvs".  And, as has been pointed out to me, it's
even allowed to append tree release or (part of) git tree ID to that string.
