so a question about the flashes everyone show how it is daylight in hawaii (zoey), night time in LA (mark), day time in london (agent geoff), and night time in kandahar (tracey and her dad) this means that janice was getting her sonogram done at night in LA, which doesnt make any sense, unless she was somewhere else.

In Kandahar it wasn't night real the only problem is with London and Hawaii. But I still like Flash Forward and I think they still can give some explanation. I hope they will!! BTW LOST also don't have logic sense.
