A fast ISO8601 date parser for Go

[![GoDoc](https://godoc.org/github.com/relvacode/iso8601?status.svg)](https://godoc.org/github.com/relvacode/iso8601) ![Build Status](https://github.com/relvacode/iso8601/actions/workflows/verify.yml/badge.svg) [![Go Report Card](https://goreportcard.com/badge/github.com/relvacode/iso8601)](https://goreportcard.com/report/github.com/relvacode/iso8601)

```

go get github.com/relvacode/iso8601

```

The built-in RFC3333 time layout in Go is too restrictive to support any ISO8601 date-time.

This library parses any ISO8601 date into a native Go time object without regular expressions.

## Usage

```go

package main

import "github.com/relvacode/iso8601"

// iso8601.Time can be used as a drop-in replacement for time.Time with JSON responses

type ExternalAPIResponse struct {

	Timestamp *iso8601.Time

}

func main() {

	// iso8601.ParseString can also be called directly

	t, err := iso8601.ParseString("2020-01-02T16:20:00")

}

```
