DESCRIPTION
     The elftc_timestamp() function returns a timestamp supplied by the
     SOURCE_DATE_EPOCH environment variable, or the current time provided by
     time(3) if the environment variable is not set.

     The timestamp argument specifies a pointer to the location where the
     timestamp will be stored.

RETURN VALUES
     Function elftc_timestamp() returns 0 on success, and -1 in the event of
     an error.

ERRORS
     The elftc_timestamp() function may fail with the following errors:

     [EINVAL]       SOURCE_DATE_EPOCH contains invalid characters.

     [ERANGE]       SOURCE_DATE_EPOCH specifies a negative value or a value
                    that cannot be stored in a time_t.
     The elftc_timestamp() function may also fail for any of the reasons
     described in strtoll(3).
