This script applies to RARBG lists:

• it converts torrent timestamps to relative format in local timezone. Also, it recalculates them every 10 seconds.
• The initial timestamps are still available as tooltips (on mouse hover), also converted to local timezone.

Note: there's a timestamp on the footer of each RARBG page e.g. Mon, 02 Nov 2020 12:23:26 +0100.
Based on that, the script takes that for the server the UTC/UTC DST offsets are +01:00 +01:00 (=no DST), therefore the timezone in the above case GMT-1.
Examples:

+01:00 +01:00 (=no DST) ---> 'Etc/GMT-1';
+02:00 +02:00 (=no DST) ---> 'Etc/GMT-2';

It uses moment.js.
