When I try to set it to the today's date, I get the message "Invalid date/time, data exists for this period."
But data does not exist for this period. Oddly, I get the same message no matter what date I try to set, even if I go far into the future.
Any advice out there? Thanks very much.

Hmmmmm, very interesting. The other day, as a test, I changed the time on my S9 forward one hour, and then back one hour, with not one bit of data lost. I just tried it again with same result. Since daylight saving time is coming up next weekend I will post a procedure tomorrow or Wednesday on how to change the time on the S9, and do it safely. But I want to do it first just to be sure, so I'll actually get a 5 day head start on DST!
