from my initial searches, "les temps des villes" seems to be a topic discussed more in France and Italy than in English-speaking countries but there are a few hits for "time policy" that seem to fit the context. If you need a clever-sounding name for the meetings, how about "it's about time."

A large number of Italian cities now have time policies, including Milan, Genoa, Rome, Florence, Venice, Pisa and Bologna.

Time policy has also been taken up in Germany an Austria where the Tutzing Time Ecological Project considers time policy from an ecological perspective.

Urban Time Policy

In a collection of essays on urban time policy published in Germany we can read that the main aims of the Italian urban time policies are: (1) to improve the relationship between occupational time and time for domestic and family labour; (2) to increase the possibilities for individuals to arrange their time structures in different ways and thus increase the usefulness of urban resources for inhabitants and improve their life quality; (3) to promote and improve opportunities for the involvement of all family members in domestic and family labour (an equal opportunities agenda for men and women); (4) the consideration and support of natural times and rhythms (biological rhythms like the natural rest phase at night, cosmological times like day and night, winter and summer); (5) consideration and support for traditional times for cities (the order of events for family and social life); (6) the promotion of the transition from standardised worktimes for work times flexible to the needs of the individual; (7) to offer city users (commuters, tourists, business visitors) hospitality in a way which considers their different time needs from permanent city inhabitants; (8) upgrading and reviving peripheral streets and squares through traded activities (including changing open hours): (9) to commit public and private services to meet two different time requirements - those of their users and those of their staff - the latter of which also require services ( equal treatment for all citizens); (10) strengthening the effectiveness of public administrations by public opening and availability at hours needed by citizens; (11) to connect time policies to the different needs of citizens at different ages of their lives.
