Advancing the clock on your computer, or "Time Travelling" is not the best thing to do. There are many posts in different forums discussing this. LDW Administration has put warnings out about the consequences that can go beyond hurting your game but in fact can hurt your computer system or other software.

If you would like to do research on this topic, I would use the SEARCH feature of this forum and type in "Time Travel" (in quotes) and set the date range for anything NEWER THAN 2 YEARS. You will get some returns that do not have to do with time travelling but you should be able to find most that are.

There are debates on this subject for and against but LDW remains firm on the use of "Time Travel". It really isn't worth it. People are going to do what they want and nobody can stop them from time travelling but is it worth the risk?
