Information compiled KompasTekno from The Independent, Thursday (20/4/2017) mentioned that WhatsApp apply the time window for five minutes to perform "unsend" message.
Users can retrieve sent messages before the five-minute period expires. However, if it is too late, the message will still be sent.
