I hope I considered anything, but it seems as if the time of the AO-Server has a forerun of approx. 15 mins.

It's confusing and doesn`t look very professional to the intended audience. It shouldn't be a big problem to synchronize via NTP with a timeserver. Correct me if I'm wrong - I do not want to step on anyones feet (and loose my few positive AntiPoints ...)

With kind regards
