does time($HOUR/YEAR) in oozie dataset support calculate such as $(HOUR-4)？

For example ,  URL in dataset is  “/${HOUR}" and current HOUR=10:00 , can
we use it to generate time 6:00 ?  such as  ${HOUR-4} or  ${HOUR}-4 ? or
other methods ?  Thanks.

That's an interesting use-case, but not supported this way yet.The EL constants HOUR,DAY,MINUTE etc will resolve to either the nominal time of the coordinator action or the current time, based on whether your dependencies are using coord:current(n) or coord:latest(n) respectively. You might have to adjust your 'n' value to say e.g. coord:current(-4) to achieve the desired effect.
