In My Settings/Options, I can choose a date/time format, but only by choosing a language. The format for Canada is dd/mm/yyyy, and the format for U.S. is mm/dd/yyyy. Being in Canada, and seeing both formats on a regular basis, I never know what I'm looking at! The best way to resolve this is to change my date formats to yyyy/mm/dd. I customize my dates to this whenever possible, for example, my operating system's control panel.
Unfortunately, FogBugz isn't letting me do this! Can there be an option to specify the yyyy/mm/dd format for dates? It's the only sane date format :) It even sorts textually, which makes it easier on my programmer eyes.
