Equivalent to the "highest" time period type (currently Month). This may be subject to change

Each time period is aggregated into 15 minute blocks starting at HH:00, HH:15, HH:30 and HH:45
THIS IS NOT SUPPORTED AS OUR AGGREGATE PROCESSING SCHEMA SERVICE CURRENTLY FORCES ALL ROWS TO HOUR GRANULARITY FOR PERFORMANCE OPTIMISATION REASONS (grouping to reduce db writes)
IF WE EVER NEED TO SUPPORT 15 MINS, THEN WE NEED TO CHANGE THE LOGIC THAT IS CURRENTLY APPLIED TO THE DATETIME FIELDS IN THAT AGGREGATE PROCESSING SCHEMA SERVICE

Each time period is aggregated into 1 hour blocks starting at HH:00 for every hour in the day

Each time period is aggregated into 24 hour blocks starting at 00:00 for every day in the year

Each time period is aggregated into 1 month blocks starting at 00:00 on the first of each month
