How to compare times using specific lengths in SQLite?

Question

I have event times stored in the form YYYY-MM-DD HH:MM:SS.

What I am trying to do is find all instances of Event where it occurs more than 7 hours after the preceding Trigger. I am not sure the easiest way to do this after reading the SQLite Date documentation. I guess I will have to use strftime somehow, but I'm really not sure how to approach it.

This is the basic query I'd have to build off of:

SELECT * FROM Event WHERE Event.DateTime (is more than 7 hours after) (SELECT Trigger.DateTime FROM Trigger WHERE Event.DateTime > Trigger.DateTime)

I have the test data currently set up like so:

DROP TABLE IF EXISTS "Event";
CREATE TABLE "Event" ("DateTime" TEXT, "ID" INTEGER PRIMARY KEY  AUTOINCREMENT  NOT NULL  UNIQUE );
INSERT INTO "Event" VALUES('2000-01-01 08:00:00',1);
INSERT INTO "Event" VALUES('2000-01-01 09:00:00',2);
INSERT INTO "Event" VALUES('2000-01-01 14:00:00',3);
INSERT INTO "Event" VALUES('2000-01-01 15:00:00',4);
INSERT INTO "Event" VALUES('2000-01-01 20:00:00',5);
DROP TABLE IF EXISTS "Trigger";
CREATE TABLE "Trigger" ("DateTime" TEXT, "ID" INTEGER PRIMARY KEY  AUTOINCREMENT  NOT NULL  UNIQUE );
INSERT INTO "Trigger" VALUES('2000-01-01 00:00:01',1);
INSERT INTO "Trigger" VALUES('2000-01-01 10:00:01',2);

so it should return 1, 2 and 5 from the events since those are the ones that are over 7 hours after a trigger.
