I don’t know about “only UTC" for events that are also visited locally, but giving the UTC time as well would be a good idea. Even more so for a event that is days from a local time zone change. Beyond UTC, I would normally point to http://datatracker.ietf.org/meeting/agenda-utc and its “display in browser time” feature here as well, but the latter seems to be broken by a missing file right now.
