How to view total editing time updated in Real time in Word 2007

The total amount of time that a document has been edited is useful for lawyers, consultants, and other professionals who bill for their time.
Knowing how long you have spent working on a document enables you to provide a more accurate accounting of your time.
If you have a time budget that you’re trying to stick to, you may find yourself constantly checking the document’s Properties dialog box to view the Total editing time value.
Rather than wasting time performing that chore, add the EditTime field to your document.
Word’s EditTime field displays the total time, in minutes, that the document has had the system focus (and, presumably, has been edited) since the time at which the document was
created. This is the same as the Total editing time value displayed in the Statistics tab of the document’s Properties dialog box.
Follow these steps to add some code that displays the total editing time with the word minutes added for clarity:

1. Type some descriptive text (such as Total Editing Time).
2. Press Ctrl+F9 to start a new Word field (signified by the { and } braces).
3. Between the field braces, type the following:
EDITTIME # “0 minutes” * mergeformat
4. Press F9 to complete and update the field.

Now all you have to do is update the field (or simply press F9) to check the total editing time instead of going in the properties tab to see total time worked on the document.
