When is the Island now?
A buddy of mine read my theory, ‘The Incident’, and brought up the question of “Where does Faraday’s flashback (of him working on the construction of the Orchid station) fit in all this?” Note that the scientist, Dr. Pierre Chang, makes an appearance during this flashback, dating it sometime in the late 70s early 80s (evident by comment of Andre7 on ‘The Incident’ theory).
On a side note, Faraday’s flashback also supports my theory on the remaining Losties disguising themselves as Dharma employees (see ‘Jin in a Dharma Suit?’). But back to the question of ‘When is the island?’
My buddy also pointed out that young Widmore was working in the Orchid tunnel as well. So sometime during the discovery of the Frozen Donkey Wheel and ‘The Incident’, Widmore leaves the Island (willingly or forcefully we don’t know yet). Assuming Widmore is in his mid to late 20s, and he leaves the island by 1981 (before the Dharma initiation films are copyrighted), this puts his age in the late 50s. Remember, Widmore does not age from the 1950s to the time he leaves the island because the island stops your aging (see ‘Who is Richard Alpert’). 28-30 years is plenty of time to have a grown daughter and become filthy rich. So the time period of late 70s and early 80s sounds about right.
