Hi,

You could try to use UIDefaultValueForSetChangedOnPublish configuration option. The similar question was on the forum before:

Hi, but i need a specific date, not the date i publish the page. If i use SetChangedOnPublish then i get the date when the page is publish

I found that in ContentSaveDB the change date and a publish date could be overriden by using UseIChangeTrackingSaved.

But instead of setting Changed property try to set Saved property.  The code is below.

var writablePage = page.CreateWritableClone();
 
writablePage.Saved = theNewDate;
 

EPiServer.BaseLibrary.Context.Current[ContentSaveDB.UseIChangeTrackingSavedKey] = new object();

DataFactory.Instance.Save(writablePage, SaveAction.Publish);
