6.5 Data fields related to period for primary allocation and secondary processes
This section includes the following fields:
| 45 | Time interval |
| 46 | Resolution |
Data Field (45) Time interval
| No. | Field Identifier | Description |
| 45 | Time interval | This information provides the date and time of the start and end of the reported period. |
| Description of Accepted Values | Type | Length | Examples |
| ISO 8601 date format using UTC time format. | Date and Time | 41 | 2009-03-01T13:00:00Z/2010-05-11T15:30:00Z |
This field identifies the start and end date and time of the time interval of the period in question. The time of the start and end of the period is expressed in UTC.
There may be several period classes for a time series. The overall time interval covered by the period shall be within the complete rights time interval. The number of periods within a time series as characterised by the resolution must completely cover the period’s time interval. If a time series is suppressed then the interval quantities are all zeroed out.
This field is mandatory.
Data Field (46) Resolution
| No. | Field Identifier | Description |
| 46 | Resolution | The resolution defining the number of periods that the time interval is divided (ISO 8601). |
| Description of Accepted Values | Type | Length | Examples |
| The resolution is expressed in compliance with ISO 8601. For example PT15M expresses a 15 minute resolution. | Date and Time | PnYnMnDTnHnMnS | PT15M |
This field identifies the number of periods that the time interval is divided. Where nY expresses a number of years, nM a number of months, nD a number of days. The letter “T” separates the date expression from the time expression and after it nH identifies a number of hours, nM a number of minutes and nS a number of seconds.
This information defines the resolution of a single period. The time interval must contain a whole number of periods as expressed by the resolution.
This field is mandatory.
