Fake the system time for single applications

The libfaketime library allows users to modify the system time that an application "sees". It is meant to be loaded using the dynamic linker's LD_PRELOAD environment variable. The faketime command provides a simple way to achieve this.


Install the latest version of libfaketime as follows:

guix install libfaketime

Or install a particular version:

guix install libfaketime@0.9.10

You can also install packages in augmented, pure or containerized environments for development or simply to try them out without polluting your user profile. See the guix shell documentation for more information.
