DATES variable

This variable is being provided as an alternative to the DATE variable since verion 10.08.  It provides more flexibility and has simpler options relative to the DATE variable. 

Example use:
$%DATES::yyyy-MM-dd  HH:mm:ss%$   would return 2013-07-04  12:08:56
$%DATES::MMMMMMMMMM%$   would return  March or April or September or December  depending on the month
$%DATES::MMM%$   would return  Mar or Apr or Sep or Dec  depending on the month
$%DATES::MM%$   would return  03 or 04 or 09 or 12  depending on the month

DATES is based on the java SimpleDateFormat class.  The description below is taken from the java SimpleDateFormat class.

Date and time formats are specified by date and time pattern strings. Within date and time pattern strings, unquoted letters from 'A' to 'Z' and from 'a' to 'z' are interpreted as pattern letters representing the components of a date or time string. Text can be quoted using single quotes (') to avoid interpretation. "''" represents a single quote. All other characters are not interpreted; they're simply copied into the output string during formatting or matched against the input string during parsing.

The following pattern letters are defined (all other characters from 'A' to 'Z' and from 'a' to 'z' are reserved):
