A fast ISO8601 date parser for Go

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

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")
}
