Essential Tools Module classes RWTimeTuple and RWTimeTupleOffset also represent dates and times and can be used as an alternative to RWDateTime in some circumstances. These classes store a tuple of each calendar component of a date and time. If you need picosecond precision or don’t need to perform calculations and comparisons of dates, these classes may offer better performance. For more information, see “Date and Time Classes” in the Essential Tools Module User's Guide.
