Calculator Problem: Adding decimal hours to a date

We are performing this opreation in Java today. However, Iwould like to try and move this calculation into Kettle using the built-in steps. However when we perform the time additions using the Calculator step, we are not getting the expected results.

For instance 02/13/2014 + 0.88 hours should give us 02/13/2014 00:52:48. However we are getting 02/13/2014 01:00:00. We perform a lot of hardware date/time measurements so the granularity of the time is important.


Adding that we are using the following calculation [Date A + B Hours]

Any suggestions?

Thank You
