Hello Murray,

you must open the notebook, get the notebook expression, change 

CellChangeTimes, create a noteboook object from the expression. The 

following code does this:

nbo=NotebookOpen["d:/tmp/Untitled-1.nb"];

nb=NotebookGet[nbo];

nb= nb /. HoldPattern[CellChangeTimes->{__}]->CellChangeTimes->{};

NotebookPut[nb,nbo];

Finally you may save the notebook by hand or automatically by:

NotebookSave[notebookname]

If you do not want to see the notebook, you may give to option 

Visible->False to NotebookOpen

hope this helps, Daniel
