A bit of searching at MSDN:
strftime: Here the format strings for strftime on win systems are listed.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt_strftime.2c_.wcsftime.asp
setlocale:
Country/Region Strings
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt_country_strings.asp
Language Strings:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt_language_strings.asp
To "fight" many user notes about strftime and setlocale on win, it might be useful to add link to this sites.
Any thoughts?
If this directly applies to PHP on windows, then it would be good to include.
