 In the Tor Browser build process, we are using some helper scripts to
 generate zip and tar archives reproducibly. Those helper scripts expect
 the modification time of the included files to be reproducible, which is
 the case when we are using libfaketime during the builds.

 To be able to remove the use of libfaketime in some parts of the build
 process and still generate reproducible archives, we could update the
 helper scripts to change the time of all files included in the archives
 according to `$REFERENCE_DATETIME`.
