Hmm! and one hour difference is not detected, because of the way is being parsed. Why would that happen? Why would %S be in the range second (00..60), instead of (00..59)?: seks00=1698539400; TZ=Europe/Berlin date -d '@1698539400' '+%Y%m%d%H%M%S' seks02=1698543000; TZ=Europe/Berlin date -d '@1698543000' '+%Y%m%d%H%M%S' diff_seks=$(( seks02 - seks00 )) echo "// __ \$diff_seks: |$diff_seks|" https://man7.org/linux/man-pages/man1/date.1.html %Y year %m month (01..12) %d day of month (e.g., 01) %H hour (00..23) %M minute (00..59) %S second (00..60) ~ C
