Golang时间比较

Golang中比较时间的方法有：Before、 After、 Equal, 但是都需要转成time类型来比较。

时间是否相等

1.  
   timeStr1 := "2023-01-18 08:50:29"
2.  
   timeStr2 := "2023-01-18 08:50:29"
3.  
   time1, err := time.Parse("2006-01-02 15:04:05", timeStr1)
4.  
   time2, err := time.Parse("2006-01-02 15:04:05", timeStr2)
5.  
   if err == nil && time1.Equal(time2) {
6.  
   fmt.Println("相等")
7.  
   }

时间A小于时间B

1.  
   timeStra := "2023-01-16 08:50:29"
2.  
   timeStrb := "2023-01-17 08:50:29"
3.  
   timea, err := time.Parse("2006-01-02 15:04:05", timeStra)
4.  
   timeb, err := time.Parse("2006-01-02 15:04:05", timeStrb)
5.  
   if err == nil && timea.Before(timeb) {
6.  
   fmt.Println("小于")
7.  
   }

时间A大于时间B

1.  
   timeStra := "2023-01-16 08:50:29"
2.  
   timeStrb := "2023-01-15 08:50:29"
3.  
   timea, err := time.Parse("2006-01-02 15:04:05", timeStra)
4.  
   timeb, err := time.Parse("2006-01-02 15:04:05", timeStrb)
5.  
   if err == nil && timea.After(timeb) {
6.  
   fmt.Println("大于")
7.  
   }
