I have. Replacing the battery seems to help for maybe a month, then it goes back to giving garbage for date/time. The process remains working even though the date/time is jumping all over the place. I get tons of task I/O Overlap minor errors, but this is "legacy product and no longer supported". I gave up trying to fix the date/time issue... I just clear out the minor errors every so often and remind superiors this controller is obsolete.
