Today is NOT when Skynet goes online.
- In Terminator, the original online date was 4th Aug 1997.
- In Terminator 2: Judgement Day the destruction of Miles Dyson's lab put it back to July 2004.
- In Terminator 3: A Turgid Pile Of Shite, events caused it to go online a year earlier in July 2003.
- At the start of The Sarah Connor Chronicles, Cameron states the online date was today (21 April 2011)
- At the end of The Sarah Connor Chronicles, Catherine Weaver's time jump led to Judgement Day changing again (and John Connor never even led the resistance)
- Between The Sarah Connor Chronicles and Terminator: Salvation, Time got back on track with John leading the resistance with Judgement Day now in July 2004,
- Events in Terminator: Salvation first reset Judgement Day to July 2002, before finally settling it as going online in 2005.
