Go's timing date cycle date setting processing and conversion to timestamp

example

package main
import (
	"fmt"
	"time"
)
func main() {
    
    
        var tt int64 = 1512230400
        ts := time.Unix(tt, 0)
        tst := ts.AddDate(0, 1, 0) //年、月、日（可以为正、负）
        fmt.Println(ts)
	fmt.Println(tst)
}
