Am I the only one? 41-CX clock question

[hth]

I cannot really say for sure why, but I lose clock sometimes. But I have not felt it is related to battery changes, it is more random.

Put it this way, I have never felt it to be all that rock solid. It can work for weeks without problems, but it happens from time to time. I have a feeling that it is more frequent these days as the calculator gets older, but that is just a hunch.

The clock is a bit like the HP-41 is by design, it takes active measures to ensure that the data is correct. If the system suspect something is wrong, clear it. It has a hardware bit as well as a warm start constant and if something seems fishy, you lose the clock. I was not so happy with this behavior in the past, but I think I kind of grown to accept it. The HP48 tries its recover memory and leaves the system half corrupt instead, I do not think that it was a step forward. On the other hand, while the HP48 clock is more solid, its memory system is not.
