shortYearCuttoff
Set the cutoff year for determining the century for a date (used in conjunction with dateFormat 'y'). If a numeric string only ('0'-'99') is provided then this value is used directly. If a string value has a '+' then it is added to the current year. Once the cutoff year is calculated, any dates entered with a year value less than or equal to it are considered to be in the current century, while those greater than it are deemed to be in the previous century.
Default value
+10
Valid values

Example
+20: If the current year is 2015, years 00 to 35 are considered to be years 2000 to 2035. 36 to 99 are considered to be 1936 to 1999.
