I've noticed this a few times, but when booking with someone in another timezone (which can even be within miles), it'll show the book time to me as if it were in their timezone, which causes confusion.
So like if say someone books at 7pm my time which would be 8pm their time, it would show the booking to me as being at 8pm for me... it doesn't happen consistently though, I've just seen it twice (sometimes it works right), and I don't remember if it's only after I book or after they book.
Has anyone else run into this?
