public class MDateManipulationAccessor
extends AbstractReadSourceAccessor

This accessor allows to perform operations on dates (or time), i.e. adding year(s), month(s), day(s), hour(s), minute(s), second(s) or milli(s) to a provided date.
Added values might be negative.
Accepted date formats are all the ones available in the JDK (java.util.Date, Calendar, SQL types, ...).
For the Java time package to be handled, the JDK8 extension must be included in the classpath.
The source might be iterable, in which case the result will be too.
This accessor also handles modifying all members of a Collection, in which case it will return a new Collection instance.
