I’m in Germany. I just sent a message to a buyer who is in China.
My first message’s time stamp showed 17:02 but it’s 16:02 here.
The immediate reply of the buyer showed 17:02 as well.
I then sent a custom offer right away which has the time stamp 14:03.
(It’s a 1-day delivery order too, I guess I should see what the deadline says… okay, it says 23 h 52 m, so at least that seems to work)
