/*** Convert a timestamp into a prompt time string.

There is a small problem here, that is, the natural day time spans the actual day time, there may be yesterday's time does not show yesterday, but is displayed as HH: mm, so the test came to the door, change the requirement. Change the condition from 2 minutes to 24 hours to 2 minutes to within today.

The requirement here is changed

* No display within 2 minutes
* 2 minutes-Today HH: mm
* Yesterday HH: mm
* HH: mm the day before yesterday
* MM: dd hh: mm this year
* Last Year, MM: dd hh: mm
* Year before MM: dd hh: mm
* Farther away: yyyy: MM: dd hh: mm

This is not a big problem. The question is how the cross-year situation should be. The message received three minutes before. 001, that is, the message displayed as yesterday or last year. If the receiving time of information is longer than the time, how to display it.

After some hard work, I finally finalized it. Here, I want to modify the product again and ask the product to be the final version.
