This issue indicates that the modified-time is set based on the "Last-Modified" header: #9386

I'm not sure that setting the modified-time produces much value. I downloaded one video and the mtime is exactly one year earlier than the date on the YouTube page. I downloaded another and the mtime is set to now. If the timestamp isn't intuitive, predictable, or what people otherwise expect it to be, then it seems useless and confusing.

I'm +1 for killing it. It seems like most people would prefer passing the switch to disable it if they knew how truly unpredictable it could be. Thoughts?
