Love this module, since it makes Views Aggregation work the way it really should.
The Smart Date module ( https://www.drupal.org/project/smart_date → ) is a replacement for the Core Date Ranges that extends capability, but more importantly it stores dates as timestamps rather than how the Date module stores them, which means in theory it should be compatible with this module.
We tinkered a bit with trying to get it to work, but had no luck, but may try again in a month or two.
Each Smart Date row is a compound of four pieces: delta, start time, end time, and duration. Smart date also offers each of these as a discrete renderable/filterable field in Views. Start and End date are stored as timestamps, so would be the ideal targets for this formatting.
It also offers start and end dates as contextual filters, which seemed to mostly work in our limited testing.
