golang如何设置时间

// 已当前时间为基增长年/月/日后的时间对象

timerAdded := timer.AddDate(1, 2, 3)

curYear, curMonth, curDay = timerAdded.Date()

fmt.Printf("current date: %d-%02d-%02d\n", curYear, curMonth, curDay)

// 以当前时间为基增长N纳秒后的时间对象 比如增长了一天

timeDuration, _ := time.ParseDuration("24h")

timerAdded = timer.Add(timeDuration)

// 计算两个时间的差值 返回的是纳秒 按需求自行计算其他单位

// Duration is type of int64 and nanoseconds

timeDuration = timerAdded.Sub(timer)

fmt.Printf("days duration between %s~%s: %d\n",

    timerAdded.Format(timeLayout),

    timer.Format(timeLayout),

    timeDuration/1000/1000/1000/24/60/60)

// 使用时间串获取时间对象

timer, _ = time.Parse(timeLayout, "2018-08-08 08:08:08")

// 使用时间串获取时间对象 并设定时区

timer, _ = time.ParseInLocation(timeLayout, "2018-08-08 08:08:08", timeLocation)

// 使用Unix时间戳构建时间对象

timer = time.Unix(1552368806, 0) //2019-03-12 13:33:26的Unix时间戳

fmt.Println(timer.Format(timeLayout))

// 获取当前时间是本年第几天 本周第几天

fmt.Printf("year day: %d, week day: %d\n", timer.YearDay(), timer.Weekday())

// 使用表征字符串转换时间跨度

timeDuration, _ = time.ParseDuration("300s")

fmt.Printf("nanosecond: %d\n", timeDuration)

timeDuration, _ = time.ParseDuration("300us")

fmt.Printf("nanosecond: %d\n", timeDuration)
