Hi Andre,
I did follow the instructions very carefully, at least 10 times.
By the way, the instructions say, that I don't have to unregister the server before making a new registration, this should be done automatically.
I also made my own example, it did work, but with the actual time as timestamp.
Is it possible, that I changed some configurations elsewhere in my system which could cause this behaviour ?
I will not be in office next week, so I can't make new experiments.
Thank you for helping
Thomas
