Format OffsetDateTime converted from JAXBElement<XMLGregorianCalendar>

I am trying to convert the JAXBElement-XMLGregorianCalendar to offsetDateTime. I am able to do that but I want to convert the date in a particular format.

Code I am using to convert: calendarValue is 2016-03-25T00:00:00+05:30 but i need to convert the type to offsetDateTime so I am doing below conversion

calendarValue.toGregorianCalendar().getTime().toInstant().atOffset(ZoneOffset.UTC)

In response I am getting the value after converting as: 2016-03-24T18:30:00Z while I want the converted value as: 2016-03-25T00:00:00+05:30.

Could anyone pls help to get the desired conversion of dateTime.

tl;dr

myXMLGregorianCalendar
.toGregorianCalendar()
.toZonedDateTime()
.format( 
    DateTimeFormatter.ISO_OFFSET_DATE_TIME 
)

Details

Convert an XMLGregorianCalendar legacy object to another legacy class, GregorianCalendar as an intermediate step. 

GregorianCalendar gc = myXMLGregorianCalendar.toGregorianCalendar() ;

Convert to the modern class.

ZonedDateTime zdt = gc.toZonedDateTime() ;

This ZonedDateTime object may meet your needs.

Generate a string representing the value of this moment in your desired format, though your format unfortunately masks the name of the time zone which is valuable information. 

String output = zdt.format( DateTimeFormatter.ISO_OFFSET_DATE_TIME ) ;

But if you want to see that same moment adjusted to UTC, just extract a Instant. 

Instant instant = zdt.toInstant() ;

If you need the more flexible OffsetDateTime class, apply an offset.

OffsetDateTime odt = instant.atOffset( ZoneOffset.UTC ) ;
