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

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")
}

Release History

• 2.0.0

Time range validity checking equivalent to the standard library. Note that previous versions would not validate that a given date string was in the expected range. Additionally, this version no longer accepts 0000-00-00T00:00:00 as a valid input which can be the zero time representation in other languages nor does it support leap seconds (such that the seconds field is 60) as is the case in the standard library

• 1.1.0

Check for -0 time zone

• 1.0.0
