Added additional catch-all case for timestamp based versioning

Prior commit reported version 2.9.1.236 for all timestamps greater-than
or equal to the 2.9.1.236 timestamp. I realized this might break the
versioning logic for later 2.9 SW versions, so I added an additional
version tuple of (2.9.1.9999) to represent those versions instead.
