If you need some data points...

apache's mod_log_config says the following:

%...{format}t 	The time, in the form given by format, which should be
in strftime(3) format. (potentially localized)

python also seems to use a similar format:

http://docs.python.org/library/datetime.html#strftime-strptime-behavior

so does ruby:

http://www.ruby-doc.org/core/classes/Time.src/M000392.html

and java:

std.log doesn't need this ASAP because support for this can be added
later but it would be nice to have.
