Split into multiple chunks of 4 seconds from a continuos stream creates almost infinite chunks after some hours

Summary of the bug:
How to reproduce:

% ffmpeg -loglevel error -threads 0.5 -stimeout 5000000 -rtsp_transport tcp -i rtsp://rtsp-server-1:8900/22de326b-2f8e-42c5-904c-d30263072d60 -strftime 1 -c:v copy -c:a copy -f hls -hls_flags delete_segments -hls_time 4 -start_number 0 -hls_allow_cache 0 -hls_list_size 32 -hls_segment_filename %Y-%m-%d_%H-%M-%S.ts playlist.m3u8

Currently we have a process recording continuously from a rtsp stream, we are splitting the input into 4 seconds chunks with a total of 32 chunks.
After some hours the process stops rotating the chunks and creates an "infinite" file that consumes all the remaining space of the hard disk.
