It's important to remember also that you can be well over the limit the next day. It takes about an hour for the body to process a unit of alcohol, so if you had say ten pints, approx 20 units and started drinking at 8 o'clock, it would be 4 o'clock the next day before it's all out of you system.
It would be half four. You should always leave it half an hour after you consume to start counting down your units.
Out of the two options, only one has ever crossed my mind.
