Report Designer uses default formats for dates and numbers. You can
change how dates and numbers display by selecting the object (field) and selecting the
appropriate value for the format from the drop-down list next to
format (under Attributes). In the example
below, the dates associated with the Order Date field will display as
MM-dd-yy.

Note: You can type a value for your own format if you know the correct JavaScript string
nomenclature.
