	// zone. The time being formatted must be in UTC for Format to
	// generate the correct format.

https://www.cnblogs.com/sandea/p/9696712.html 时间可分为时间点与时间段 ,提供了以下两种基础类型 - 时间点(Time) - 时间段(Duration)

除此之外 golang 也提供��了以下类型，做一些特定的业务 - 时区(Location) - Ticker - Timer(定时器)

const (
	// 时间常量,按照平时年历的计数方法,不考虑闰年闰月之类的
	Day   time.Duration = time.Hour * 24
	Week                = Day * 7
	Month               = Day * 30
	Year                = Day * 365
)

Functions

func AtFunc

func AtFunc()

func CurrentUnixMillis

func CurrentUnixMillis() int64

返回当前系统时间戳,基于毫秒单位

func Format

func Format(layout string, t time.Time) string

func FormatCommon

func FormatCommon(t time.Time) string

func GetNow

func GetNow() string

func GetNow2TargetTime

func GetNow2TargetTime(targetTime time.Time) (time.Duration, error)

获取现在的时间 距离 目标时间之间 剩余时间段,

func GetNowDate

func GetNowDate() string

func GetNowTime

func GetNowTime() string

func GetTarget2NowTime

func GetTarget2NowTime(targetTime time.Time) (time.Duration, error)

获取过去时间 到 现在时间 的时间段

func GetTimeFormat

func GetTimeFormat(duration time.Duration) string

Truncate returns the result of rounding t down to a multiple of d (since the zero time). If d <= 0, Truncate returns t stripped of any monotonic clock reading but otherwise unchanged. 按照常规使用字符串 "yyyy-MM-dd HH:mm:ss" 来格式化时间.

func GetTimeRound

func GetTimeRound(duration time.Duration) (time.Time, error)

func GetTwoTimeSub

func GetTwoTimeSub(startime, endtime time.Time) (time.Duration, error)

返回两个时间段时间的 时间段

func HowCost

func HowCost(start time.Time, limit time.Duration, limitFunc CostCallFunc)

use example :

func test() {
	defer HowCost(time.Now(), time.Second, LogCostCallFunc)
	// do some work
}

func HowCostInTrack

func HowCostInTrack(start time.Time, limit time.Duration, track interface{}, limitFunc CostCallFunc)

func ParseLocal

func ParseLocal(targetTimeStr string) (time.Time, error)

func ParseMillSecond

func ParseMillSecond(millSecond int64) time.Duration

将毫秒单位的时间段转换为 以纳秒为单位的time.Duration类型对象

func ParseSecond

func ParseSecond(second int64) time.Duration

将秒单位的时间段转换为 time.Duration类型对象

func Time_UnixMillisecond

func Time_UnixMillisecond(millisecond int64) time.Time

毫秒单位的时间戳转换为time类型 1ms == 1000us (微秒) 1us == 1000ns (纳秒) 1ms == 1000us * 1000ns == 1*10^6(ns)

func Time_UnixSecond

func Time_UnixSecond(second int64) time.Time

秒单位的时间戳 转为 time类型

func UnixMicrosecond

func UnixMicrosecond(t time.Time) int64

返回unix时间戳,基于微秒单位

func UnixMillisecond

func UnixMillisecond(t time.Time) int64

返回unix时间戳,基于毫秒单位

func UnixSecond

func UnixSecond(t time.Time) int64

返回unix时间戳,基于秒单位

Types

type CostCallFunc

type CostCallFunc func(realCost time.Duration, track interface{})

var (
	EmptyCostCallFunc CostCallFunc = func(realCost time.Duration, track interface{}) {

	}
	LogCostCallFunc CostCallFunc = func(realCost time.Duration, track interface{}) {
		fmt.Println(realCost)
	}
)

type JsonTime

type JsonTime struct {
	time.Time
	// contains filtered or unexported fields
}

func NewJsonTime

func NewJsonTime(t time.Time) JsonTime

func NowJsonTime

func NowJsonTime() JsonTime

func (JsonTime) MarshalJSON

func (jt JsonTime) MarshalJSON() ([]byte, error)

所以我们只需定义一个内嵌time.Time的结构体，并重写MarshalJSON方法，然后在定义model的时候把time.Time类型替换为我们自己的类型即可。但是在gorm中只重写MarshalJSON是不够的，只写这个方法会在写数据库的时候会提示delete_at字段不存在，需要加上database/sql的Value和Scan方法 https://github.com/jinzhu/gorm/issues/1611#issuecomment-329654638。

func (JsonTime) String

func (jt JsonTime) String() string

func (*JsonTime) UnmarshalJSON

func (jt *JsonTime) UnmarshalJSON(data []byte) error

type TimeUnit

type TimeUnit time.Duration
