实现如果在在一个秒级时间戳上加上23h59m59s

先把时间戳转换成 time 对象,然后利用 Add 函数在该对象上添加23h59m59s,最后获取时间对象的时间戳

package main

import (
	"fmt"
	"time"
)

func main() {
	// Suppose you have a timestamp in seconds
	timestampSecs := int64(1627468293)

	// Convert the timestamp to the time.Time
	t := time.Unix(timestampSecs, 0)

	// Add 23h59m59s
	t = t.Add(23*time.Hour + 59*time.Minute + 59*time.Second)

	// If you need to convert it back to a timestamp in seconds:
	timestampSecsUpdated := t.Unix()

	fmt.Printf("Updated timestamp in seconds: %v\n", timestampSecsUpdated)
}

注意

最好不要单纯的给 时间戳加上整数来修改时间戳,比如像下面这样,不仅看着费劲,也容易出bug

timestampSecs := int64(1627468293)
targetStamp := timestampSecs + time.Duration(3600 * time.Hour*23) + time.Duration(60 *time.Minute * 59) + time.Duration(60 * time.Second)
