// 6.1.3. Extended Timestamp
// This field is transmitted only when the normal time stamp in the
// chunk message header is set to 0x00ffffff. If normal time stamp is
// set to any value less than 0x00ffffff, this field MUST NOT be
// present. This field MUST NOT be present if the timestamp field is not
// present. Type 3 chunks MUST NOT have this field.

// FMLE always sendout the extended-timestamp,
// must send the extended-timestamp to FMS,
// must send the extended-timestamp to flash-player.
