 Summary of the bug: looks like it's not possible to have start_time after
 95379. It resets.
 How to reproduce:

 {{{

 ffmpeg -y -fflags nobuffer \
     -v 9 -loglevel 99 \
     -rtsp_transport tcp \
     -i 'rtsp://login:pass@host:554/cam/realmonitor?channel=9&subtype=1' \
     -use_wallclock_as_timestamps 1 \
     -reset_timestamps 1 \
     -avoid_negative_ts 1 \
     -vcodec copy \
     -movflags frag_keyframe+empty_moov+genpts+discardcorrupted \
     -hls_flags append_list \
     -f hls \
     -segment_list_flags live \
     -output_ts_offset 95379 \
     -hls_time 1 \
     -hls_list_size 3 \
     -hls_segment_filename ./v9/%06d.ts ./v9/index.m3u8

 Wait 10 seconds and interrupt command.

 Then:

 $ ffprobe -v error -show_entries format=start_time,duration -of
 default=noprint_wrappers=1:nokey=1 000000.ts
 95383.420000
 1.860011

 $ ffprobe -v error -show_entries format=start_time,duration,start_pts -of
 default=noprint_wrappers=1:nokey=1 000001.ts
 -58.297689  <- overflow
 1.860011
