The events in the DS9 episode
What We Leave Behind took place at Stardate 52902.0 which is Wedesday, 26 November 2375 05:31:12 GMT
The events in
Endgame took place at Stardate 54973.4 which is Thursday, 22 December 2377 06:59:02 GMT
The Voyager episode closest to the events in
Dogs Of War must be
Relativity which took place at Stardate 52861.274 which is Tuesday, 11 November 2375 08:45:36 GMT, the same day as the events in
Dogs of War.
The Voyager episodes closest to
What We Leave Behind must be
Warhead or
Equinox #1. None of those episodes has any Stardate (sloppy work from those in charge) but in the book Star Charts by Geoffrey Mandel,there is a Stardate 52900 written near the sun FGC 509006.
Close to that sun is another sun called Salina with a planet called Salina Prime which is mentioned in the Voyager episode
Warhead. So we can assume that the events in
Warhead took place at Stardate 52900 which is Tuesday, 25 Nov 2375 12:00:00 GMT which is one day before the events in
What We Leave Behind.
