"The high council is in emergency session. They have plans of their own--"
"To hell with the high council; their plans have already failed!"
This all happened concurrently with the events of "The End of Time" -- during the siege of Arcadia, Timothy Dalton (disguised as Rassilon) was trying to enact the plan to escape the time lock and ascend to a higher plane of existence by destroying the universe, but David Tennant stopped that from happening and restored the time lock, leaving Gallifrey to burn when John Hurt unleashed the full power Billy Piper. But then Matt Smith and another David Tennant stopped John Hurt and Billy Piper from destroying Gallifrey by removing it from reality. Presumably Peter Capaldi will pull Gallifrey out of stasis next season, and then... who knows whether they'll address Timothy Dalton. Possibly it'll get sort of forgotten, like who blew up the TARDIS.
(It was Santa robots. Santa robots are going to turn out to have blown up the TARDIS.)
And, yeah, the general guy was speaking hastily when he said the High Council's plans had already failed; he meant it more figuratively, as in "Those useless idiots couldn't possibly have anything worth hearing about." The events of "The End of Time" took place between the Doctor's theft of the Moment and Gallifrey's destruction/vanishing.
EDIT: Oh, and the David Tennant bits of Day of the Doctor seem to take place between "The Waters of Mars" and "The End of Time."
