FWIW, everything is working fine here.

But I don't understand what "the hour display in emacs calendar" means,
or what your "system hour" is. Can you specify *exactly* what you do?

How do you set the timezone?

----------------------------------------------Thank you for your answer.See the following test:1) When I C-u C-c . to insert Date and Time format, the following option is shown:

I press RET and the following Date+time is inserted:<2016-05-22 So 20:50>As you see, the inserted time is different.But if I call the agenda the current time is shown properly:


2) When I change the timezone to UTC in my computer (not in emacs) there is no problem to inserta Date+time. However, it is not a solution because it changes emacs clock, agenda, ... etc. I made that change justfor testing purposes.
