Hi Marc,
What you are referring to is not so much off-peak in the old sense, but time-of-day metering.
We have 3 rates, Peak, Shoulder and Off-Peak with different rate for each category.
Peak = 2pm-8pm
Off-peak = 10pm-7am
Shoulder all other times
Weekends and public holidays are either shoulder or offpeak.
