 The basic way of running any command/program with libfaketime enabled is to

+On Linux, library search paths can be set as part of the linker configuration.
+LD_PRELOAD then also works with relative paths. For example, when libfaketime.so.1

 However, also the faked time should be specified; otherwise, libfaketime
 will be loaded, but just report the real system time. There are three
