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

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

时间A小于时间B

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

时间A大于时间B

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