if it has been a full 24 hours, then you can set the time to 11:59, but not until it's been 24 hours. Lets say you had the babies at 10am yesterday, then at 10:01 today, you could change the time to make them leave. I always give them an extra hour, like for my previous example, I would wait till 11am. this is just to ensure that it happens. I also write down the time they had the babies, just so i don't get confused, thinking they had babies at 8am, but it really wasn't until 10am. Make sense?
