Shoshonnah helpfully notes: as close to 9:00 as possible (for you Americans who don't use a 24-hour clock, that's 9:00AM).

Lessee, 24 hour clock, umm, subtract 12 hours... if the answer is non positive add them back, umm, 9 minus 12 is dumm de dum dum By George! She's right! nine o'clock is nine o'clock!
