Heres how I got it figured, maybe I missed some things though...
I've only got the VHS full screen versions of T1-3, so don't catch all the details of DVD or wide-screen versions, but tried to ID where I got the info from in every case possible...
T1- 1984 Present Day according to the opening scene Time Stamp... Thursday, May 12, according to the cop who Kyle Reese encounters before breaking into the store to steal guns and more clothes...
'What day is it? The date?'
"Thursday... May 12..."
"What year?!?" no response because sirens sound, scaring Reese into the store.
T1 spans only about 3 days, 4 nights, so its still May 1984 at the end.
T2, I never did see a date printed anywhere, including on the police car computer when the T-1000 is tracking down John. Saw him find John's address and birthdate (Feb 28, 1985), and the stupid AGE:10 thing, which is where I would say the error was made. I would say T2 was set in 1997, so yeah, Sarah would have already been diagnosed with Lukemia by then, if they hadn't only just invented that for T3, and yeah she would have been fighting just to survive the last 3 years since being diagnosed in 1994, sure sure... except, I also would believe that the whole lukemia thing was another trick to fool Skynet into thinking Sarah was also 'off the grid' and that John was weakened, and took himself off the grid, and therefore no longer a threat to Skynet and the histiry of things to come... I think Sarah and John were happily living life in Baja (as they were 'living in Baja when she was diagnosed' according to John in T3) when Sarah read something on the new advances at Cyberdine, which got her going... so she and John packed up and returned to the LA area, and she attacked the cyberdine computer research facility, to blow it up, but got caught and sent to Pescadero state hospital... What about at the hospital sessions with Silberman, where SArah mentions the exact date of Judgement Day, and talks about it in the future tense? you may ask...
'We all have dreams Sarah, and sometimes dreams can seem quite real..'
'Well on August 29, 1997 it's going to seem pretty ****ing real to you too! Anyone not wearing 1-million sunblock is going to have a real bad day! get it?!'
Remember, this is a videotaped session, reviewed by Silberman and Sarah at her current review, to discuss and decide if she has shown improvement... apparently, according to Silberman's statements, they do the reviews about every 6 months or so, so possibly the session they are watching was from 6 months or more ago, maybe before August 29, 1996... so Sarah didn't just say '...on August 29th it will seem pretty real...' she added the year, 1997 to the date... see??
so, set T2 in 1997, possibly late 1996, then the only flaws are when the T-800 is explaining the history of things to come, when he says Dyson discovers things and gets skynet going in a few months, then in 3 years skynet becomes self-aware, etc etc... you could say that T-800 is talking in future tense about things that are current news, because he doesn't realize it, and that judgement day is really only a few months off at the time he's explaining all that, so it COULD be 1997 at that time, making John 12 or 13 or so, which appears more accurate... right? T2 spans only about 2 days and 3 nights, so still 1997 at the end...
which sets T3 in 2007, 'a decade has passed', '10 years ago' various references in T3 state that it's been 10 years since Judgement Day was postponed... John's 22 or 23 now, which appears accurate still too, and T3 also states somewhere that John was 13 at the time of T2, so it's still accurate... I dont have it written if it lists Sarah Connors death date on her marker, but its not really important I dont think... probably sometime after August 29, 1997 though because it's stated that she wanted to be certain Judgement Day didn't happen on that day, so she 'fought the lukemia'/stayed 'on the grid' at least that long, before dying/disappearing...
T3, I don't know if anyone noticed or if it's been discussed in any other forum, but the whole movie appears to take place over the course of 1 night and 1 day... whereas the other 2 movies spanned at least 2 or 3 days and nights, which adds to the explanation of why things seem to move so fast, aside from the obvious non-stop wall to wall action and chases... there's no extra scenes of exposition and resting and recovering, no hot steamy sex between John and Katherine one night while they hide out in a cheap roadside motel, because they never spend another night together after meeting each other that first night, 10 years after sharing their first kiss, until they get stuck in Crystal Peak together at 6:18pm the following afternoon!! The whole movie covers just 1 day! T3 should have been called Judgement Day, since that's the only day that was covered in the course of the movie!!
any way, I've only seen T3 about 4 or 5 times, and like I said, only on VHS full screen so maybe I missed some things, but I think it covers all the various timeline loopholes, plot holes, and other holes y'all have come up with... I'm sure there's a simpler explanation, like Director C is God and Director M sucks ass or something, but c'mon, let's not go there again, huh? enjoy the friggin' movies for what they are, and stop trashing them for such little things as 'the plane's call letters were different when it was in the air than they were when it was in the hangar, so the movie sucks, Mostow's a jerk, Stahl's a wuss, Arnold's an old fart, Daines needs to get a so-called life, and they need to stop making Terminator movies if all they do is make them stupid!'
Sorry if I went off on a tangent or a rant... I haven't posted to any boards in awhile, so I have lots of pent up 'postings' in me... 🙂
wanna read my T4/T5 idea?? maybe some other post...
