Here’s what you do: send it at a round number hour, like 1am, 2am, whatever. Used a scheduled text if you wish.

Then schedule another text to be sent like 7-17 minutes later, apologizing that you accidentally sent the gif as a scheduled text for later, instead of sending it on the day of at whatever time: “omg, that was supposed to be yesterday afternoon, not 1am, so sorry!”.

Profit.
