求2个字符串对比

func CompareTime(t1, t2 string) bool {
    FORMAT := "2006-01-02 15:04:05"
    T1, err := time.Parse(FORMAT, t1)
    if err != nil {
        panic(err)
    }
    T2, err := time.Parse(FORMAT, t2)
    if err != nil {
        panic(err)
    }
    if T1.Sub(T2).Hours() == 24 {
        return true
    }
    return false
}

@hellsam 根据你的需要来，有可能需要改成 xx == 24 || xx == -24

https://github.com/Juntaran/Go_In_Action/tree/master/Demo/TimeChina 可以用这段转成时间戳再对比

package main

import (
    "fmt"
    "os"
    "time"
)

func main() {
    a0 := "2017-12-16 21:04:53"
    a1 := "2017-12-13 21:04:53"
    a2 := "2017-12-12 21:04:53"
    var err error
    var t0, t1, t2 time.Time
    layout := "2006-01-02 15:03:04"
    if t0, err = time.Parse(layout, a0); err != nil {
        fmt.Errorf("error while parse time:%v\n", err)
        os.Exit(1)
    }
    if t1, err = time.Parse(layout, a1); err != nil {
        fmt.Errorf("error while parse time:%v\n", err)
        os.Exit(1)
    }
    if t2, err = time.Parse(layout, a2); err != nil {
        fmt.Errorf("error while parse time:%v\n", err)
        os.Exit(1)
    }
    ONE_DAY := time.Hour * 24
    fmt.Printf("a0和a1相差大于一天吗? %v\n", t0.Sub(t1) > ONE_DAY)
    fmt.Printf("a2和a1相差大于一天吗? %v\n", t2.Sub(t1) > ONE_DAY)
}
