dateformat required for JDEDATE field in Callobject XML request

Hi,

While executing the BSFN through xml request, in which date format we should send the value for JDEDATE type field.?

I tried with different one  -

'2009-08-05T01:01:01.001'

'8/04/2009'

'2013-10-01T00:00:00-06:00'

but i didnt see value for this specific field in JDEDEBUG logs.

ex.

<?xml version='1.0' encoding='utf-8'?>

<jdeRequest type='callmethod' user='JDE' pwd='JDE ' environment='JDV920' session='' sessionidle=''>

<startTransaction trans='tn1' type='manual'/>

    <callMethod app='' name='F4101ProcessMasterData' trans='tn1' runOnError='no' returnNullData='yes'>

        <params>

            <param name='szUnitOfMeasureProduction'> </param>

            <param name='cTaxableYN'> </param>
