Git's source code refers to timestamps as unsigned long, which is ill-defined, as there is no guarantee about the number of bits that data type has.
In preparation of switching to another data type that is large enough to hold "far in the future" dates, we need to prepare the t0006-date.sh script for the case where we *still* cannot format those dates if the system library uses 32-bit time_t.
