// When we save the document to an OOXML format, we can create an OoxmlSaveOptions object
// and then pass it to the document's saving method to modify how we save the document.
// Set the "UpdateLastSavedTimeProperty" property to "true" to
// set the output document's "Last saved time" built-in property to the current date/time.
// Set the "UpdateLastSavedTimeProperty" property to "false" to
// preserve the original value of the input document's "Last saved time" built-in property.
OoxmlSaveOptions saveOptions = new OoxmlSaveOptions();
saveOptions.UpdateLastSavedTimeProperty = updateLastSavedTimeProperty;

doc.Save(ArtifactsDir + "OoxmlSaveOptions.LastSavedTime.docx", saveOptions);

if (updateLastSavedTimeProperty)
    Assert.That(DateTime.Now, Is.EqualTo(lastSavedTimeNew).Within(1).Days);
    Assert.AreEqual(new DateTime(2021, 5, 11, 6, 32, 0),
