A DESCRIPTION OF THE REQUEST :
The javax.xml.DatatypeFactory interface allows for creation of durations with BigDecimal seconds but only allows BigInteger seconds for day-time durations. It needs to have the following method:
Duration newDurationDayTime(boolean isPositive, BigInteger day, BigInteger hour, BigInteger minute, BigDecimal second)
JUSTIFICATION :
Having a BigInteger instead of a BigDecimal argument is inconsistent with both the newDuration constructor (that does take a BigDecimal seconds) and the documented behaviour of Duration.getField, which returns BigDecimal for the seconds field. It also makes it impossible to correctly implement a downcast from duration to day-time duration according to the XPath2 spec and without prior knowledge of implementation precision limitations.
CUSTOMER SUBMITTED WORKAROUND :
The only way to create a day-time duration with fractional seconds at the moment is to use the newDurationDayTime(long millis) factory method.
