Sometimes you need more than seven minutes to unsend a message on WhatsApp. Thankfully, with the most recent update, now we do. The most recent patch (2.18.31) extends the "delete for everyone" period to one hour, eight minutes and 16 seconds according to a tweet from the messaging service. Is that oddly specific amount of time a reference to anything? It seems like it is, but as far as we know, it isn't. We do know one thing for sure: Telegram users have 48 hours to delete a message and save face before anyone else sees it, so WhatsApp still has some catching up to do. Both are still more generous than GMail's 30-second unsend feature though.
