Date parameter returns week number minus 1

[mtibbi]

I am trying to configure calendar dates.list to include the week number in date information. But parameter %W is returning actual week number minus 1. The same occurs for %U.

For instance:
%d/%m/%Y (week %W) returns 31/08/2015 (week 35)
but this date should be in week 36.

I am adding a screen capture of the time stamp produced by two different setups for the week.

One setup is using %W and another is using %U.

Both setups should return the week number 38, as shown in the headline of the page, but they are returning 37 instead.

%d/%m/%Y (week %W)
16/09/2015 (week 37)

%d/%m/%Y (week %U)
16/09/2015 (week 37)

Testing zim 0.64 on windows 7, US locale, seems to behave as expected. Code inspection I see this formatting is done directly by python's own datetime.strftime function, not modified by zim itself.

No clue how to pinpoint.

I tried to reproduce the failure with Zim 0.65 on Windows 10, BR-PT locale. Also tried with Zim 0.63 portable on previous machine with Windows 7, BR-PT locale. In both cases I was unable to reproduce the problem.
