Your idea has a lot of support, AMG, and I certainly see a strong need for an international time standard that we can all agree on when organizing race events. As someone pointed out, it will still be necessary when private races are introduced. However, I don't see a need to integrate the clock into the header. If anything, I may include GTP Standard Time in the footer, with a link to a page containing the official clock, a local time conversion tool, and more information about how to use it. With that said, GTP Standard Time (GTPST) will be GMT in a 24 hour format. That will make conversions for everyone about as simple as it can get.
