.. to apologise and admit an error publicly like you did, even though in our eyes this was just an accident and is really not a big issue anyway. People make mistakes and a mistake with time zones are just very common and easy. Especially on this forum, I think a few of the fellow Purists already know about the news even before you announced it and the impact is just very minimal. Yet you chose to write an open apology to Lange for the sake of trust, respect, and correctness, it takes courageous good man to do that.
I'm also happy that Lange appreciate your continuous contribution to our community and is being very gracious about this.
One word for all the parties involved - Class!
