* This method implements the following logic: If the event is a paste, the
* pasted text is parsed for the entire date/time selection; if this parse
* is successful, the result is committed to the selection property and is
* displayed; otherwise, it is discarded. One-character pastes are discarded
* without parsing. When user types characters one by one, all non-digits
* are discarded (if they have effects, they have already been processed by
* other event handlers) while digits are added to
* <code>this.editField</code> without affecting the selection. Once
* <code>this.editField</code> reaches its capacity for the active field,
* its contents are attempted to be committed. If the commit is successful,
* focus switches to the next field of CDateTime. Otherwise, the contents of
* <code>this.editField</code> are discarded and the previous value of the
* selection (before user started typing in this field) is restored; focus
* stays in the same field. <b>Example:</b> if the seconds field contains
* "23", and user types 8 in the seconds field, "08" is shown on screen
* while getSelection still returns 23. If user types 9 after that, the
* field reaches its capacity, the attempt to commit 89 seconds fails, and
* 23 gets restored on screen.
*
