Star Trek: The Next Generation

Episode	Departure	Destination	Time travelers	Method
"We'll Always Have Paris"	The USS Enterprise-D (as well as the USS Lalo, the Coltar IV colony, and the Ilecom system) experiences several short time loops (the Manheim Effect) in this episode caused by a "window" into another dimension.
"Time Squared"	2365	6 hours earlier in 2365	Jean-Luc Picard (aboard the shuttlepod El-Baz)	energy vortex
"Yesterday's Enterprise"	2344	2366	USS Enterprise-C with crew	temporal rift

	22nd century	2368	Berlinghoff Rasmussen (aboard a time-pod)	temporal distortion
	2368	26th century	A time-pod	temporal distortion
"Cause and Effect"	2278	2368	USS Bozeman with crew	temporal rift
	The USS Bozeman was trapped in a temporal causality loop since 2278. The USS Enterprise-D was trapped for only 17.4 days.
"Time's Arrow"	2368	1893	Two Devidians and Data	temporal distortion
	1893	2368	Two Devidians	temporal distortion
	2368	1893	Two Devidians, Jean-Luc Picard, William T. Riker, Deanna Troi, Geordi La Forge, and Beverly Crusher	temporal distortion
	The two Devidians apparently made many trips before and perhaps during the episode to 1893 that were not shown, via temporal distortion.
"Time's Arrow, Part II"	1893	2368	the male Devidian, William T. Riker, Deanna Troi, Geordi La Forge, Beverly Crusher, Samuel Clemens, and Data's headless body	temporal distortion
	2368	1893	Samuel Clemens	temporal distortion
	1893	2368	Jean-Luc Picard	temporal distortion
"Tapestry"	2369	2327	Jean-Luc Picard's consciousness and Q	Q powers
	2327	2369	Jean-Luc Picard's consciousness and Q	Q powers
	2369	2327	Jean-Luc Picard's consciousness and Q	Q powers
	2327	2369	Jean-Luc Picard's consciousness and Q	Q powers
	It is possible that the time traveling in the episode was all an illusion by Q.
"Timescape"	Time is slowed considerably before being reversed due to being trapped in a temporal fragment. Both the USS Enterprise-D and a Romulan warbird were trapped, and a runabout with Jean-Luc Picard, Deanna Troi, Geordi La Forge, and Data entered the fragment.
"Firstborn"	~2410	2370	Alexander Rozhenko	unknown
	2370	~2410	Alexander Rozhenko	unknown

	2370	3.5 billion years ago	Jean-Luc Picard and Q	Q's power
	3.5 billion years ago	2364	Jean-Luc Picard's consciousness	Q's power
	This time traveling in the episode may in fact be an illusion by Q. It is also unknown how many trips Picard made before he became aware of it (his memory was getting better with each trip).
