Is it possible to allow ArithmeticOperators and ProjectionOperation to have date as argument for subtract and add operation ? [DATAMONGO-1675]

[spring-projects-issues]

Shiv Veeram opened DATAMONGO-1675 and commented

valueOf method for add & subtract in ArithmeticOperators along with minus & plus methods on ProjectionOperation currently expects Number value, AggregationExpression or a fieldReference.

This is the shell equivalent { $subtract: [ new Date(), "$created" ] }

valueOf("created").subtract(new Date()) is not possible in ArithmeticOperators 

We've to use something like valueOf(aggregationOperationContext -> new BasicDBObject("$subtract", Arrays.asList(new Date(), "$created"))) to pass two date values.

Let me know if you need more information.
