[I] [Feature Request]: Calculator - add Date generator (hop)

["dave-csc (via GitHub)" <gi...@apache.org>]

dave-csc opened a new issue, #4554:
URL: https://github.com/apache/hop/issues/4554

   ### What would you like to happen?
   
   In the Calculator transform there are many operations to get and modify the various parts of a Date (year, month, day of month, day of week, etc.), ma no operation to get a Date object from its parts (year, month, day of month).
   
   It could be useful to add an operation like "Create Date from Year A, Month B and Day of month C": the time part can be defaulted to midnight (and then modified with the already existing operations "Date A + B hours/minutes/seconds").
   
   The current workaround consists in using a User Defined Java Expression transform, and create a field of type `Date` with an expression like:
   `new java.util.GregorianCalendar(YEAR_FIELD, MONTH_FIELD - 1, DAY_OF_MONTH_FIELD).getTime()`
    _(beware of the -1 in the month field!)_
   
   ### Issue Priority
   
   Priority: 3
   
   ### Issue Component
   
   Component: Hop Gui, Component: Transforms

   Note: I updated the workaround, since the `Integer` value in Hop is actually a `Long`/`long` type in Java rather than an `Integer`/`int`
