Comment (by hackeron):

 There seem to be a lot more errors like this:

 {{{
 [segment @ 0x19a5e20] Non-monotonous DTS in output stream 0:1; previous:
 12466764, current: 12460908; changing to 12466765. This may result in
 incorrect timestamps in the output file.
 [segment @ 0x19a5e20] Non-monotonous DTS in output stream 0:1; previous:
 12466765, current: 12462998; changing to 12466766. This may result in
 incorrect timestamps in the output file.
 [aac @ 0x1a45b80] Queue input is backward in time
 }}}

 But the output video time doesn't grow so I guess it is related to
 libfdk_aac.

 This is the full command I'm using:

 ffmpeg -use_wallclock_as_timestamps 1 -rtsp_transport tcp -i
 'rtsp://86.146.232.61/proxyStream' -dn -map 0 -acodec aac -strict -2 -ar
 44100 -codec:v copy -f segment -segment_time 60 -segment_wrap 10
 -segment_list_flags live -segment_list_size 10 -reset_timestamps 1
 -segment_list test.csv -y 'test_%02d.mkv'
