Sources are given below that wall and they may be more pleasant to read. 
There are a lot of blog posts describing various pitfalls related to 
date and time.

Timestamp format you have chosen is ambiguous.

TZ=Europe/Berlin date -d '@1698539400' '+%Y%m%d%H%M%S'
20231029023000

TZ=Europe/Berlin date -d '@1698543000' '+%Y%m%d%H%M%S'
20231029023000

You had issues with setting time and timezone, so '+%s' may give 
incorrect results.
