So, I do what all car owners do...I Google it. I found that if the battery is not installed according to the Infiniti step-by-step procedure, this issue with the clock and Homelink is result.
To install the battery, all electrics must be in the off position, including the auto-on-off headlights. The ground battery cable must be removed first (we know that). Care must be taken not to create a short by allowing the ground cable to touch the positive cable. (we know that too).
The dealer mechanic's failure to follow procedure blew a fuse. The fuse is the 6th from the top, left side, in the fuse block on the kick panel near the parking brake pedal. It is a 10 amp fuse marked ELEC PARTS (BAT). It is the only one on the diagram in black with white print. I removed the 10 amp fuse and inserted the spare that is in the box and ALL IS WELL.

So, if you are in need of a new battery, make sire the guy at Auto Zone or wherever knows what he is doing or if you do it yourself, make sure everything is turned off.
