jsUtils.isDate()

jsUtils.isDate( str )
  str - any javascript variable

Returns true if the variable is a valid date or false otherwise.

The input variable is treated as a string representing date in the US date format (mm/dd/yyyy). This string is tested to be a real calendar date and will return true is the date is valid. The function correctly interprets leap years. More date formats will be added.
