This has been an issue for a while. Time stamps have been, for whatever reasons, rather problematical for BP, one instance occurring in the activity stream was corrected, yet later I too noticed the issue re-surface in sent messages, I did establish all relevant timezones were correct when the issue first manifested so it’s unlikely to be the server timezone at fault but it does need to be ruled out. I thought that there was a ticket on this? But might be imagining it.
