Question 2.1.44 Data Fields (49) and (50)
We would like to know whether is possible to report instead of a time of 24:00:00 for end times, the indication 00:00:00. This applies to Fields 28 (contract trading hours) and Field 54 (Load Delivery Intervals).
<deliveryProfile>
<loadDeliveryStartTime>00:00:00</loadDeliveryStartTime>
<loadDeliveryEndTime>24:00:00</loadDeliveryEndTime>
</deliveryProfile>
That we can use to mean the same thing
<deliveryProfile>
<loadDeliveryStartTime>00:00:00</loadDeliveryStartTime>
<loadDeliveryEndTime>00:00:00</loadDeliveryEndTime>
</deliveryProfile>
This is consistent with the interpretation for gas contracts available in the TRUM where start time = end time.
deliveryProfile>
<loadDeliveryStartTime>06:00:00</loadDeliveryStartTime>
<loadDeliveryEndTime>06:00:00</loadDeliveryEndTime>
</deliveryProfile>
Answer
According to ACER’s schemas and to the ISO 8601 standard which says “Midnight is a special case and may be referred to as either "00:00" or "24:00"). It is our understanding that midnight may be represented as either 00:00:00 or 24:00:00 or 23:59:59.
All of them have the same meaning. The same applies to 06:00:00 and 05:59:59. All of them have the same meaning. The same applies to 06:00:00 and 05:59:59 to represent the end of a gas day.
