Generally, it has a lot to do with when the trade is called in/registered with the league. Take the Patty Kane trade for instance. Everyone knew about it and the details 2 hours before it actually happened. But because the teams had to wait until 4 PM CST to make the money work, they didnt call it in with the league / it wasn't officially registered. Since this trade was practically a complete secret until the moment it happened, it didnt take very long between hearing about it and it being registered with the league
