Subject: isofs: prevent file time rollover after year 2038
Date: Thu, 20 Oct 2022 18:00:29 +0200
Change the return type of function iso_date() from int to time64_t, to
avoid truncating to the 1902..2038 date range.
After this patch, the reported timestamps should fall into the range
reported in the s_time_min/s_time_max fields.
