What's it like to receive a text message from the future?

When sending a message, it will automatically mark the time of the message. One is that the sender's mobile phone can automatically mark the time, and the other is that the operator's server will automatically mark the time. So there are two possibilities:

1, there is something wrong with the sender's mobile phone time;

2. There is a problem with the time of the operator's server.

Of course, the first situation is the most likely to happen, which is why mobile phone manufacturers are unlikely to adopt this as a standard.

So it can be inferred that it should be the second case.
