This is a forum manned by volunteer fans who are all in different time-zones, not a chat-room, so I'm afraid that you won't always be able to get an answer right away. Posting multiple threads also won't speed this up, unfortunately.
The simple answer is that the version you're playing does not have a pause feature like some later models do - it's a remake of the original Tamagotchi releases from 1996/1997, which didn't offer this. It is possible to put the clock into "Set" mode at any time, which acts as an unofficial pause feature, but that's already been described by the kind user @Dogfish in the other thread that you posted a couple of minutes before posting this one, so I'm going to lock this one now.
