Are you talking about changing a specific section to another date time format in your own version of intrapages or are you reporting a bug?
I know there som inconsistency regarding date time format, probably because I have not found a good way make it work for all different browser langugages.
in the best of worlds all dates should be displayed in the format you have set in your browser or in the language setting in the application, but I am not there yet.
Thanks
