This is probably one of the easier things to do in Flex. Yea you could probably find out how to do this by reading the Adobe Flex Documentation but who wants to read that when you have Google at your fingertips.

What the Adobe Flex Documentation wont tell you is how to format your date and time inside of a DataGrid or other components.  No worries I do!

Here is how you format a date pulled in as XML, E4X or whatever…

First you will need a DateFormatter

<mx:DateFormatter id="formatDateTime" formatString="MM/DD/YY" />

 

the formatString will determine how your date & time is formatted. I have created a pattern chart below that’s a little easier to read then the one on Adobe’s Flex Documentation.

OK now on to applying it to a date with funky database formatting 

formatDateTime.format(yourDateTimeObjectAsString);

For playing around purposes I created an example in Flex, change the pattern to alter the date and time

Almost forgot!, To use the format inside of a DataGrid you need to add

<mx:DateFormatter id="formatDateTime" formatString="MM/DD/YY" />

to your DataGrid inside of a VBox or HBox along with your label so it looks something like this

<mx:DataGridColumn headerText="Date">
     <mx:itemRenderer>
          <mx:Component>
               <mx:VBox>
                    <mx:DateFormatter id="formatDateTime" formatString="MM/DD/YY" />
                    <mx:Label text="{formatDateTime.format(data.myDate) }/>
