Fake the system date
This program (and preload library) fakes the system date so that programs think the wall clock is ... different.
The faking is not complete; timestamp on files are not affected in any way.
This package is useful if you want to test the date handling of your programs without changing the system clock. Examples: Does it handle expired certificates correctly? Does it work on a leap day?
