strftime("%z") not working correctly

[3e4]

I am running vim 4.7.1913 on Windows 7, and using Python 3.5 as default python interpreter.

%z and %Z yield the same result in the strftime() statement.

:echo strftime("%z __ %Z")
W. Europe Daylight Time __ W. Europe Daylight Time

This is a wrong behavior based on Man page of strftime. This issue might be related but only a workaround for calendar.vim was discussed.

The man page isn't relevant for Windows.

%z isn't a standard strftime format code. The (SU) at the end of the description indicates that it is an extension from the initial specification introduced by the Single Unix Specification.

Microsoft treats %z and %Z the same.

Thank you for this clarification. I was not sure it's implemented in Windows or in vim itself. Guess I'll have to live with it.
