Steps to reproduce: - Use two devices with a 1h clock offset - Add both to a private group - Exchange messages - In the device which is behind, all messages will show a time of "now" This is very confusing and makes it difficult to notice that the devices clocks are off. Possible solution: show "invalid time" instead, to help the owner of the misconfigured device notice the issue. The correct solution is #1098, but even if that were in place, there may be cases where this could help, and I can't think of it doing much damage.
