Usage

File Times for #golang

Go has a hidden time functions for most platforms, this repo makes them accessible.

package main

import (
  "log"

  "github.com/alist-org/times"
)

func main() {
  t, err := times.Stat("myfile")
  if err != nil {
    log.Fatal(err.Error())
  }

  log.Println(t.AccessTime())
  log.Println(t.ModTime())

  if t.HasChangeTime() {
    log.Println(t.ChangeTime())
  }

  if t.HasBirthTime() {
    log.Println(t.BirthTime())
  }
}

Supported Times

windows linux solaris dragonfly nacl freebsd darwin netbsd openbsd plan9 js aix
atime
mtime
ctime ✓*
btime ✓*
  • Linux btime requires kernel 4.11 and filesystem support, so HasBirthTime = false. Use Timespec.HasBirthTime() to check if file has birth time. Get(FileInfo) never returns btime.
  • Windows XP does not have ChangeTime so HasChangeTime = false, however Vista onward does have ChangeTime so Timespec.HasChangeTime() will only return false on those platforms when the syscall used to obtain them fails.
  • Also note, Get(FileInfo) will now only return values available in FileInfo.Sys(), this means Stat() is required to get ChangeTime on Windows
