Format a time or date [complete guide] � YourBasic Go, CODE EXAMPLE To format or parse a time in Go, you format a special layout parameter const ( layoutISO = "2006-01-02" layoutUS = "January 2, 2006" ) date� rfc3339 эквивалентно iso 8601. В частности, она имеет одинаковый формат, rfc3339 только имеет более строгие требования (например, требуется полное представление даты с 4-значным годом).

package main

import (
    "fmt"
    "time"
)

func main() {
    fmt.Println(time.Now().UTC().Format("2006-01-02T15:04:05-0700"))
}

iso8601, Time in JSON in ISO 8601 format, without subsecond resolution or time zone info. Index �. Replacing the sign in the format with a Z triggers the ISO 8601 behavior of printing Z instead of an offset for the UTC zone. Thus: Z0700 Z or ±hhmm Z07:00 Z or ±hh:mm Z07 Z or ±hh The recognized day of week formats are "Mon" and "Monday". The recognized month formats are "Jan" and "January".

The Go Playground, package main import ( "fmt" "time" "strings" ) func main() { // convert iso-8601 into rfc-3339 format rfc3339t := strings.Replace("2015-12-23 00:00:00", " ", "T", 1) +� Go: Format a time or date. To format a date use the Format method: func (t Time) Format(layout string) string. To parse a date string use the time.Parse function: func Parse(layout, value string) (Time, error) The layout parameter describes the format of a time value. It should be the magical reference date

ISO8601 allows for variable levels of granularity. You can have just a year, year+month, year+month+day, add a time portion, and optionally have a timezone portion. Go's built-in time parsing, however, requires you to know ahead-of-time which parts will be included.

The github.com/btubbs/datetime library provides a more flexible parser that can handle all the commonly used ISO8601 formats. See https://github.com/btubbs/datetime

Disclosure: I wrote that library.

src/time/format.go, Parse. 10 // The reference time used in the layouts is the specific time: 11 // Mon the ISO 8601 behavior of printing Z instead of an 43 // offset for the UTC zone. CODE EXAMPLE To format or parse a time in Go, you format a special layout parameter (Mon Jan 2 15:04:05 MST 2006) the same way as the time should be formatted

The service receives a Go program, vets, compiles, links, and runs the program inside a sandbox, then returns the output. If the program contains tests or examples and no main function, the service runs the tests. Benchmarks will likely not be supported since the program runs

Go: Format a time or date, How to format/parse a date or timestamp in Go. The layout parameter describes the format of a time value. It should 2006-01-02, yyyy-MM-dd, %F, ISO 8601. If you have worked with time/date formatting/parsing in other languages you might have noticed that the other languages use special placeholders for time/date formatting. For eg ruby language uses %d for day %Y for year etc. Golang, instead of using codes such as above, uses date and time format placeholders that look like date and time only.

How to convert RFC3339 format to ISO8601 in golang?, I have a timestamp which I am getting using time.Now().Format(time.RFC3339). The format is 2018-10-17T07:26:33Z However, I want the format in ISO 8601:� ISO8601 date converter. e.g. UNIX Time: "444972896789", RFC2822: "Tue, 07 Feb 1984 12:34:56 JST" => ISO8601: "1984-02-07T12:34:56,789+09:00"

Comments
  • This should be the accepted answer. The others may work, but they would certainly confuse someone who was unfamiliar with the code.
  • ISO 8601 and RFC3339 are not technically the same thing. stackoverflow.com/questions/522251/…
  • From what I could tell, RFC3339 is a stricter version of ISO 8601. So it is probably safe to use the RFC format if a system expects the ISO.
  • Note: It appears that converting to UTC first is not necessary: play.golang.org/p/UDrkigOfgIc
  • @lukeic that's because golang playground is working in UTC timezone. Try to run on your local machine.
  • What is the RFC value to get this result?
