Not in the case where you have no datestamp changes for a month, say, then
some other change is committed, but a new datestamp change hasn't yet been
committed after that other change; then you have, for a limited period, a
compiler with a datestamp value long before the last commit. (That's the
main case I can think of for not making snapshots if only DATESTAMP has
changed, rather than the simpler approach of omitting some DATESTAMP
updates and not making snapshots if nothing at all has changed.)
