   *Examples*: If the attribute "year" has the value "2014" and the attribute "time" has the value "2014/12/31 15:36:03.264Z",
  -	then the Expression `${year:toDate('yyyy')}` will return the number of milliseconds between Midnight GMT on January 1, 1970
  -	and Midnight GMT on January 1, 2014. The Expression `${time:toDate("yyyy/MM/dd HH:mm:ss.SSS'Z'")}` will result in the
  -	number of milliseconds between Midnight GMT on January 1, 1970 and 15:36:03.264 GMT on December 31, 2014.
  +	then the Expression `${year:toDate('yyyy')}` will return a Date data type with a value representing Midnight GMT on
  +	January 1, 2014. The Expression `${time:toDate("yyyy/MM/dd HH:mm:ss.SSS'Z'")}` will result in a Date data type for
  +	15:36:03.264 GMT on December 31, 2014.
   	
   Often, this function is used in conjunction with the <<format>> function to change the format of a date/time. For example,
   if the attribute "date" has the value "12-24-2014" and we want to change the format to "2014/12/24", we can do so by
  
positive.code: - *String*: A String is a sequence of characters that can consist of numbers, letters, white space, and
  	special characters.
  - *Number*: A Number is an integer comprised of one or more digits (`0` through `9`). The Expression Language 
  	does not provide support for fractional numbers. Dates and times are represented in the
  	Expression Language as Numbers, representing the number of milliseconds since midnight GMT on January 1, 1970.
  - *Boolean*: A Boolean is one of either `true` or `false`.
  
  All attributes are considered to be of type String.

  *Description*: [.description]#Converts a String into a Date data type, based on the format specified by the argument. The argument
  	must be a String that is a valid Java SimpleDateFormat syntax. The Subject is expected to be a String that is formatted
  	according the argument.#
