// .NAME vtkStringToTimePoint - Converts a string array to a integral time array
//
// .SECTION Description
//
// vtkStringToTimePoint is a filter for converting a string array
// into a datetime, time or date array.  The input strings must
// conform to one of the ISO8601 formats defined in vtkTimePointUtility.
//
// The input array specified by SetInputArrayToProcess(...)
// indicates the array to process.  This array must be of type
// vtkStringArray.
//
// The output array will be of type vtkTypeUInt64Array.
