I do not bellieve I have erver not done some programming, etc within a half
year, so my CM11A has never gone that long without being changed. That may
be why I have never seen this issue.

I have gone 2 units since the first one out last year, and they all have had
the time issue. Someone said if you do the math, the CM15A acts like it was
designed to be on a 50hz power instead of a 60hz power source. Someone
bolstered this argument by claiming the unit was designed in asis somewhere
where 50hz power is the norm.  Like I said, since it is hooked to my server
that runs 24x7, the time issue does not affect me, so the trade off for more
memory was worth it.
