Hi Rajesh,
What you need to do is format the date. Why don't you do it this way use Format method to format the date.
Try parsing it using
  
Datetime myDateTime = DateTime.parse('11/21/2014 15:20:00');
And then format the myDateTime using 
String dtConverted = myDateTime.format('MM/dd/yyyy HH:mm a'));
Note: Not tested it.

If it helps, please mark this as solved.

Try this code 
String input = '11/21/2014 15:20:00';
input = input.subString(6,10) + '-' + input.subString(0,2) + '-' + input.subString(3,5) + 'T'+input.subString(11);
DateTime dt = (DateTime) JSON.deserialize('"' + input + '"', DateTime.class);
System.debug(dt.format());

Try the following code, it will be usefull for you

<apex:outputText value="{0,date,M/d/yyyy hh:mm a }">
      <apex:param value="{!Chat.h_message_sent_on__c}" />
</apex:outputText>

Balaji - I followed your approach but the datatime value is showing 4 hours less than the actual date time. i.e it is converting the date time value to my local time zone in Salesforce UI. Could please help me here on how to get desired format without time zone.

Thanks,
Indy
