You can save the value of Date.Now at the start of your application in a global variable:

Public StartDate As Date = Date.Now

Then you can calculate the current date in your arbitrary time scale, using the TimeSpan calculated from this starting date and the current date, at any point in your code:

Dim Elapsed As TimeSpan = Date.Now - StartDate
Dim NewDate As Date = ArbitraryStartDate + Elapsed

Choose ArbitraryStartDate to be any date you like with the Date constructor like

Dim ArbitraryStartDate As Date = New Date(1983, 05, 03)
