Much copying of NT_03's Lambo guesses...Lamborghini Countach 25th Anniv. Edition

Basically, you get 4 hours to reply to someone's guess if you are the riddle-maker. However, if you need to sleep or do your job, etc. you can use "E.T." or "Extended Time" to add on roughly 8 hours (give or take) to your normal reply delay. Get it?Can someone explain how does the "E.T." system work? I didn't quite get it.
