Marked with or bearing a dateline, especially as a newspaper article that shows the place and date of publication or origin.
From 'dateline' (noun: the line at the top of a news article showing date and location) plus the past participle suffix '-ed'. The term emerged in journalism to standardize how news was credited.
Reading old datelined articles is like time travel—a 'Paris, June 15, 1944' dateline instantly tells you you're reading breaking news from D-Day's aftermath.
