go 去除时间的时分秒

实现

如 2021-12-18 12:14:16 格式化为 2021-12-18 00:00:00

func main() {
	timeNow := time.Now()
	timeNowStr := timeNow.Format("2006-01-02 15:04:05")
	fmt.Println("timeNowStr:", timeNowStr)
	// 方式一
	timeDateStr := timeNow.Format("2006-01-02 00:00:00")
	fmt.Println("timeDateStr:", timeDateStr)

	// 方式二
	y, m, d := timeNow.Date()
	date := time.Date(y, m, d, 0, 0, 0, 0, time.Local)
	dateStr := date.Format("2006-01-02 15:04:05")
	fmt.Println("dateStr:", dateStr)
}
