On one machine, my dates in Excel display as month-day-year, for example May 27, 2010 displays as 05/27/10. (This machine is Windows XP, in case that's significant. Excel 2003).
When I take that same file and open it on a different machine (Windows 7, also Excel 2003), the same date displays as 27/05/10.
Is this an Excel thing or a Windows thing? How can I fix it so the date displays the way I want it, mm/dd/yy ?
