They were one-off meetings, but I think we could have done recurring meetings with the data that we were storing. I see what you mean about the different timezones in PHP - these are based off the Olsen timezone database. I do think the best way to make users happy is to let them pick their default timezone on a personalization screen, and display it (but let them change it) along with each event that they create. This Javascript code below can get you most of the way there, but it does come with the caveat that "Not all Olson tz keys are given by this script. If there are many timezones with UTC+6 but none of them use daylight savings, this script simply returns ONE of the timezone keys representing this type of timezones." https://bitbucket.org/pellepim/jstimezonedetect/wiki/Home https://bitbucket.org/pellepim/jstimezonedetect/wiki/Home
