Trying to find a time to catch a meeting with Joe, Human Made's CTO, can be a task in itself. He is constantly on the move, which is a problem when you are not sure what timezone or location he is in. In this talk, we will look at how we can harness technologies such as GeoIP and Geolocation to keep track of him. I will be sharing how we created a WordPress plugin that integrated Foursquare, GeoIP, and the WordPress API into an internal site; the quirks and pitfalls of these technologies; and issues that have to be considered before trying to store time zones.
