------------------------------------------------------ From: Thomas Schmitt scdbackup@gmx.net 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.
