Lost : 3 aspects of Time

First of all, Time is a very special element in Lost. We can't just assume we know time as the way it is. There are at least 3 aspects of Time in Lost.

1. The Land's time: This is the normal time in our current world. As in Oceanic 816 took off from Sydney in 2004, Ajira took off in 2008 from LA and Rosseau's ship took off from Tahiti in 1988 etc. The related time period is from 1954 to 2008. Some may say it even goes back to 1845 when Jacob and MIB had a conversation watching the sail in ship, where Richard was a slave in the ship ?
2. The Island's time: This is the time occur on the Island. The time on the Island may be the same as the Land's time in the past or future. But there is a special 108 days on the Island where this whole story is all about. So the Island's time usually refers to these 108 days. This would be from 27 Sep 1997 to 13 Jan 1998.
3. A person's time. Everyone has their own time. Jack may be 34 years old when he board Ocenic 816 in 2004. Then he crashes on to the island in 1997. Jack does NOT turn younger. He is still 34 years old. As far as Jack is concern, his time stays the same. Although the environment's time has changed. More is explained in this old time travel article and the life path theory may also relate.
