Sync metadata to multiple files - how does that work?

Question

Frustrating.  In Library Module of LR4.4 under Vista 32, I have corrected a "Capture Time" of a single jpg Photo via the "Edit Capture Time" dialog.  The new date correctly shows up in the "Date Time Original" EXIF field of the Metadata panel on the right.
Now, I want to sync that date to other jpgs which all come with incorrect "Date Time Original" - so, I highlight the above photo, mark the other ones to less light grey, press "Sync Metadata".  THe dialog of  "Sync Metadata" appears, showing the new date under "ICPT image" as "date created" - so far so good.  I mark that field, and press the ok button and the sync runs.  After that, no change is shown to the respective field of any of the photos metadata fields to be sync'd, no sync has actually happened, and even the "Save Metadata to file" command does cure this situation.
Using the command with a single target file instead of multiple ones does not help either.
What does help?
Why can't I update a set of superold pictures to their correct "date created" date via Metadata sync? This Metadata sync does not sync.
thanks for comments

Well, of course, one can always take the escape route to software that works. - 
However, IF Adobe advertises "Metadata sync" in a software licensed for money, THEN this function should work. Am I right or am I right?
I found, that particularly the one single Metadata field "Capture time" can be set for a multitude of images (selected before using this command from the pulldown menue) - which helped for my problem.  But what about other Metadata fields, if the "Sync Metadata" function does not work as intended?  No word in the documentation such as "there is a function "Sync Metadata" but please do not expect ANY function at all when using it".
Using a freeware such as ExifMeta to get arund a "non-function" is not the purpose of using a software such as Lightroom - please understand.
