The Function list for a Date
column is date-specific. It allows you to decide the type of modification you want to do
on date values.

There are three different ways to generate the date value for duplicated
records:

• Modify date value: randomly selects the day,
  month or year to modify and puts a random value in place.

• Switch day month value: switches the day and
  month values. If the original day value is greater than 12, then the new month
  value will be ((N-1) mod 12) +1. For example: If the
  original day is equal to 13, then the new month is equal to 1.

• Replace by random date: generates a random
  date with day, month and year values.
