// .NAME vtkTimePointToString - Converts a timestamp array to a string array
//
// .SECTION Description
//
// vtkTimePointToString is a filter for converting a timestamp array
// into string array using one of the formats defined in vtkTimePointUtility.h.
//
// Use SetInputArrayToProcess to indicate the array to process.  
// This array must be an unsigned 64-bit integer array for 
// DATETIME formats, and may be either an unsigned 32-bit or 
// unsigned 64-bit array for DATE and TIME formats.
//
// If the new array name is not specified, the array name will be
// the old name appended by " [to string]".
