Thanks for the feedback, attached new complete patch with code changes +
added documentation for it

Please also explain why this might be required in the docs. In the commit message please name the specific vendor/device which is not parsing zero offset correctly.

I wonder if it would make sense to set this flag by default (doing that can be a separate patch) if it improves compatiblity.

One more idea is that maybe we should introduce a flag which always puts the timestamp in UTC instead? Otherwise your approach only works if the local time is UTC, no?

Thanks,
Marton

Some HLS players prefer UTC+0 timestamps in PROGRAM-DATE-TIME to end in a
Z instead of +0000, this patch adds a hlsflag to enable that feature.
Example command:
ffmpeg -i input.mp4 -c copy -hls_flags +program_date_time+zulu_timezone
output.m3u8
Example PDT output:
#EXT-X-PROGRAM-DATE-TIME:2019-10-22T10:27:54.000Z
