I'm not familiar with the OpenVMS epoch, but I don't believe
flexibility in a definition of a epoch can make it better. Where can I
read a discussion of the value of making a epoch flexible? And what on
earth does it mean to make an epoch flexible?

Yes, Shifting/rotating is what I call changing the setting on your
clock. Using words that suggest a break in the fabric of time vastly
over state the powers of Man.

Progress! in coming to see my point. You can say things about women that
you cannot yet admit about yourself. :-)
