yep, this is all kinds of wrong. G+ says 11:16, details on my phone say "2 apr 2015 23:16:05", and both are wrong. If you download the image yourself and look at the EXIF metadata, it does give the correct time, which is 01:17.
Thanks for the invite, but I was actually on my way back home. A shame though, as I was in Munich the whole week. Next time then.
