Overview

Package xtime implements time related XMPP functionality.

In particular, this package implements XEP-0202: Entity Time and XEP-0082: XMPP Date and Time Profiles.

Constants

const (
	// NS is the XML namespace used by XMPP entity time requests.
	// It is provided as a convenience.
	NS = "urn:xmpp:time"

	// LegacyDateTime implements the legacy profile mentioned in XEP-0082.
	//
	// Unless you are implementing an older XEP that specifically calls for this
	// format, time.RFC3339 should be used instead.
	LegacyDateTime = "20060102T15:04:05"
)

func Get

func Get(ctx context.Context, s *xmpp.Session, to jid.JID) (time.Time, error)

Get sends a request to the provided JID asking for its time.

func Handle

func Handle(h Handler) mux.Option

Handle returns an option that registers a Handler for entity time requests.

type Handler

type Handler struct {
	TimeFunc func() time.Time
}

Handler responds to requests for our time. If timeFunc is nil, time.Now is used.

func (Handler) HandleIQ

func (h Handler) HandleIQ(iq stanza.IQ, t xmlstream.TokenReadEncoder, start *xml.StartElement) error

HandleIQ responds to entity time requests.

type Time

type Time time.Time

Time is like a time.Time but it can be marshaled as an XEP-0202 time payload.

Example

Code:

package main

import (
	"encoding/xml"
	"fmt"
	"mellium.im/xmpp/xtime"
	"time"
)

func main() {
	t, _ := time.Parse(time.RFC3339, "2020-02-19T06:46:00-05:00")
	xt := xtime.Time(t)

	o, _ := xml.Marshal(xt)
	fmt.Printf("%s\n", o)
}

<time xmlns="urn:xmpp:time"><tzo>-05:00</tzo><utc>2020-02-19T11:46:00Z</utc></time>

func (Time) MarshalXML

func (t Time) MarshalXML(e *xml.Encoder, _ xml.StartElement) error

MarshalXML implements xml.Marshaler.

func (Time) TokenReader

func (t Time) TokenReader() xml.TokenReader

TokenReader satisfies the xmlstream.Marshaler interface.

func (*Time) UnmarshalXML

func (t *Time) UnmarshalXML(d *xml.Decoder, start xml.StartElement) error

UnmarshalXML implements xml.Unmarshaler.

func (Time) WriteXML

func (t Time) WriteXML(w xmlstream.TokenWriter) (n int, err error)

WriteXML satisfies the xmlstream.WriterTo interface. It is like MarshalXML except it writes tokens to w.
