There is a small problem here, that is, the natural day time spans the actual day time. It is possible that yesterday's time does not display yesterday, but displays HH:mm, so the test came to the door and asked to change it. The condition of 2 minutes-24 hours is changed to 2 minutes-within today.改 The demand here is changed to

* 2 minutes without display

* Yesterday yesterday yesterday hh: mm
* the day before yesterday hh: mm
* this year mm: dd HH: mm
* MM:DD HH:mm
last year * MM:DD HH:mm
the year before last year * Further yyyy:MM:DD HH:mm


This is not a big problem, the question is what will happen during New Year's Eve? , the message received in the first three minutes of 2015-01-01 00:01.001, that is, whether 2014-12-31 should be displayed as yesterday or last year. How to display the message if the reception time is greater than the time.

After a lot of arguing, it was finally finalized. Here we will modify the product again and require the product to be certified as the final version.
