代码如下
package main
import (
"fmt"
"time"
)
func main() {
const FORMAT = "2006-01-02 15:04:05"
t := time.Now()
fmt.Println(t.Location(), t.Format(FORMAT))
time.Sleep(time.Second * 10)
newTime := t.Add(time.Hour * 5) //之前时间加上5小时
currentTime := time.Now() //当前时间
if newTime.After(time.Now()) {
fmt.Println(newTime.Format(FORMAT), " 大于 ", currentTime.Format(FORMAT))
} else {
fmt.Println(newTime.Format(FORMAT), " 小于 ", currentTime.Format(FORMAT))
}
}
执行到time.Sleep(time.Second * 10)时,将电脑时间改为1天后，执行结果如下
Local 2020-03-26 14:31:36
2020-03-26 19:31:36 大于 2020-03-27 14:31:45
如果t := time.Now().Local() 加上local就没有问题
package main
import (
"fmt"
"time"
)
func main() {
const FORMAT = "2006-01-02 15:04:05"
t := time.Now().Local() //加上local
fmt.Println(t.Location(), t.Format(FORMAT))
time.Sleep(time.Second * 10)
newTime := t.Add(time.Hour * 5) //之前时间加上5小时
currentTime := time.Now() //当前时间
if newTime.After(time.Now()) {
fmt.Println(newTime.Format(FORMAT), " 大于 ", currentTime.Format(FORMAT))
} else {
fmt.Println(newTime.Format(FORMAT), " 小于 ", currentTime.Format(FORMAT))
}
}
输出了正常结果
Local 2020-03-26 14:32:20
2020-03-26 19:32:20 小于 2020-03-27 14:32:29
time.After判断上有点奇怪
