This code (for the sample below) doesn't work!
ULong addSeconds = (4 * 365.25 * 24 * 60 * 60); // add
It has two problems:
a) 365.25 (there's better ways for leap year adjustment!)
b) you have to cast the constants to long, otherwise the compiler
uses int for intermediate values and you get overflow problems
ex: 24 * 60 * 60
should be 24L * 60L * 60L
