//Commonly used in forums, for example, after posting a comment, display just now
//The rules are as follows (can be changed according to the actual situation)
1: Return to """Just now" within ten minutes
2: within today --- display how many hours ago
3: within yesterday ---- yesterday hour: minute
4: Consistently displayed as 16-11-11 11:11
