Function marshalTimeJson

query/outputnode.go:701–726

marshalTimeJson does what time.MarshalJson does along with supporting RFC3339 non compliant time zones in a timestamp. While go 1.20 changes the behaviour of time.MarshalJSON, we do not want to throw error suddenly because we can't marshal the stored data correctly any more.

(t time.Time)

// time zones in a timestamp. While go 1.20 changes the behaviour of time.MarshalJSON, we do
// not want to throw error suddenly because we can't marshal the stored data correctly any more.
func marshalTimeJson(t time.Time) ([]byte, error) {
	_, offset := t.Zone()
	// normal case
	if types.GoodTimeZone(offset) {
		return t.MarshalJSON()
	}

	// If zone >23 or <-23, we need to handle this case ourselves.
	// This is because, in go1.20, MarshalJSON fails for invalid zones.
	// We, for now, call MarshalJSON for timestamp without the zone (or making it UTC zone).
	b, err := t.Add(time.Duration(offset) * time.Second).UTC().MarshalJSON()
	if err != nil {
		return nil, err
	}

	// we will get a byte slice that has Z appended at the end along with a quote (")
	// e.g.: []byte("2018-05-28T14:41:57Z"). We replace Z with -/+.
	zone := offset / 60
	if zone < 0 {
		b[len(b)-2] = '-'
		zone = -zone
	} else {
		b[len(b)-2] = '+'
	}
	return append(b[:len(b)-1], []byte(fmt.Sprintf("%02d:%02d\"", zone/60, zone%60))...), nil
}
