I wonder if there is a subtle difference between "1" and "2"
1. Rosie - it's time to get up.
2. Rosie - it's time you got up.
#1 sounds like a wake-up notice.
#2 sounds a bit like Rose was slightly negligent in not getting up sooner.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
