Binary package “datefudge” in ubuntu trusty

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
 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?
