This endpoint provides Minimum Zero Time data received from NGESO. The Minimum Zero Time is the minimum time that a BM Unit which has been exporting must operate at zero or import, before returning to export; whereas if the BM Unit has been importing, the MZT indicates the minimum time that it must operate at zero or export before returning to import, if action by the System Operator (i.e. a Bid-Offer Acceptance) places it at such a level.
