How to modify the 0-level content display time SMS on Apple mobile phone?

Apple's mobile phone can modify the time information displayed by level 0 content as follows:

1. Open the SMS, and click the detailed option in the upper right corner-return to the SMS interface. When you open the message, you can see that the date of the message is displayed in the upper right corner, and the most recent time is at the top.

2. As long as you click on a short message, you can directly see that only the time of the top short message is specifically displayed.
