On a Windows computer with excel installed, matlab talks directly to excel to load the file. On a Windows computer without excel installed or on non-Windows computer this is not possible and a completely different method is used to load excel files. Matlab parses the file directly instead.

A downside of that is that indeed, excel dates are imported as excel serial date numbers. Here is a post on how to convert these numbers back to dates.
