[[Property:title|DATE TIME to STRING Conversion]]

The classes <eiffel>TIME</eiffel>, <eiffel>DATE</eiffel>, and <eiffel>DATE_TIME</eiffel> provide a query <eiffel>formatted_out</eiffel> which can be used to retrieve a string containing the date or time in a format specified by a string or format conversion codes that the caller provides as an argument. The conversion is done in the <eiffel>DATE_TIME_CODE_STRING</eiffel> class. So for example, if a <eiffel>DATE</eiffel> instance referenced by <eiffel>my_date</eiffel> has a value of February 3, 2008, then applying the query:
<eiffel>
            my_date.formatted_out ("[0]dd mmm yyyy")
</eiffel>
will return the string:
<code lang=text>
03 FEB 2008
