Indeed, Ed. I was about to point out that the STCKE *format* defines 8 more bits on the left -- enough to cover things through the year 9999 and beyond. Considering that the software was upgraded to support this "long" clock format, I was disappointed that it wasn't similarly updated to support those new high-order bits in its date/time conversions (and saving me from having to write the code myself). It seems to me that while the hardware may not yet use those bits, there's no reason why the software couldn't support them.
