If you want to have reproducible binaries, you may also want to alter the clock
of the sandbox system.

Suggestions:

At start, set the date as EPOCH (i.e., in 1970).

Each time a file date seems to be set in the future (by tar, ...), set the date
of the sandbox system to that date plus a milisecond.

Each time a file is created or touched, advance the date of the sandbox system
by one milisecond.
