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!
That was very brave of you to experiment! So it looks like the time can be changed without erasing the data, if you don't get the error message then it would make sense that your data would still be OK. I wonder what would happen if you tried the date +/- 1 day?
I should not be that worried about changing the time myself really as I live in Arizona where time is time, it never changes
