# Use faketime to freeze time to make for reproducible builds.
# faketime needs to have a very specific timestamp format in order to freeze
# time.  The time needs to be frozen so that the timestamps don't depend on
# the speed of the machine that the build process is running on.  See `man
# faketime` for more info on the "advanced timestamp format".  Also, force
# time to UTC so its always the same on all machines.
