Hi Menion,
so, what I did was the following: on 20.11.2016, 11:23 (Berlin time) I created two logs with Locus and uploaded them to geocaching.com as field notes. Now, the two field notes (
https://www.geocaching.com/my/fieldnotes.aspx) look look this:

So, the first field note (created with date-only option unchecked) has a time offset of +8 hours.
The second one (created with checked date-only option) has a time offset of +18 hours (minutes are truncated, due to checked option, I believe) and is even for the following day.
Now, this difference in time for the first field note is the diff between MEZ and PST, I guess, but the second diff? And, is it not possible to adjust this?
Interestingly, this problem raised about 2 weeks ago, until then, it worked pretty good.
I hope, you can explain and/or solve it...
Thanks!
Cheers, big.
