Resolution:

TIBCO ActiveMatrix BusinessWorks datetime function cuts off the trailing '0' in millisecond if it ends with '0'. TIBCO BusinessWorks follows the XPATH 2.0 specification which specifies no trailing zeros in the millisecond field of dateTime type. For canonical representations, the fractional second string, if present, must not end in '0'. The impact is that within TIBCO BusinessWorks, mapping to any dateTime type results in the truncation of trailing zeros, which is compliant with the XPATH specification.
