[issue5207] extend strftime/strptime format for RFC3339 and RFC2822

[Alexander Belopolsky]

Alexander Belopolsky <belopolsky at users.sourceforge.net> added the comment:

%O is used by POSIX spec to indicate alternative locale format.

Gnu date uses %:z 

       %:z    +hh:mm numeric timezone (e.g., -04:00)

	      %::z +hh:mm:ss numeric time zone (e.g., -04:00:00) %:::z numeric
	      time  zone  with : to necessary precision (e.g., -04, +05:30)
