Timex

Provides an enhanced time.Time implementation, and add more commonly used functional methods.

Install

go get github.com/gookit/goutil/timex

Usage

Create timex instance
now := timex.Now()

// from time.Time
tx := timex.New(time.Now())
tx := timex.FromTime(time.Now())

// from time unix
tx := timex.FromUnix(1647411580)

Create from datetime string:

// auto match layout by datetime
tx, err  := timex.FromString("2022-04-20 19:40:34")
// custom set the datetime layout
tx, err  := timex.FromString("2022-04-20 19:40:34", "2006-01-02 15:04:05")
// use date template as layout
tx, err  := timex.FromDate("2022-04-20 19:40:34", "Y-m-d H:I:S")
Use timex instance
tx := timex.Now()

Change time:

tx.Yesterday()
tx.Tomorrow()

tx.DayStart() // get time at Y-m-d 00:00:00
tx.DayEnd() // get time at Y-m-d 23:59:59
tx.HourStart() // get time at Y-m-d H:00:00
tx.HourEnd() // get time at Y-m-d H:59:59

tx.AddDay(2)
tx.AddHour(1)
tx.AddMinutes(15)
tx.AddSeconds(120)

Compare time:

// before compare
tx.IsBefore(u time.Time)
tx.IsBeforeUnix(1647411580)
// after compare
tx.IsAfter(u time.Time)
tx.IsAfterUnix(1647411580)
Helper functions
ts := timex.NowUnix() // current unix timestamp

t := NowAddDay(1) // from now add 1 day
t := NowAddHour(1) // from now add 1 hour
t := NowAddMinutes(3) // from now add 3 minutes
t := NowAddSeconds(180) // from now add 180 seconds
Convert time to date by template

Template Chars:

 Y,y - year
  Y - year 2006
  y - year 06
 m - month 01-12
 d - day 01-31
 H,h - hour
  H - hour 00-23
  h - hour 01-12
 I,i - minute
  I - minute 00-59
  i - minute 0-59
 S,s - second
  S - second 00-59
  s - second 0-59
... ...

More, please see charMap

Examples, use timex format date:

tx := timex.Now()
date := tx.DateFormat("Y-m-d H:I:S") // Output: 2022-04-20 19:09:03
date = tx.DateFormat("y-m-d h:i:s") // Output: 22-04-20 07:9:3

Format time.Time:

tx := time.Now()
date := timex.DateFormat(tx, "Y-m-d H:I:S") // Output: 2022-04-20 19:40:34

More usage:

ts := timex.NowUnix() // current unix timestamp

date := FormatUnix(ts, "2006-01-02 15:04:05") // Get: 2022-04-20 19:40:34
date := FormatUnixByTpl(ts, "Y-m-d H:I:S") // Get: 2022-04-20 19:40:34
