Stream Youtube with mpv starting at an arbitrary point later in the video

I prefer streaming Youtube videos via mpv, mpv https://www.youtube.com/watch?v= However, for long videos sometimes the audio breaks down in the middle, leaving error messages like > [ffmpeg] tls: Error in the pull function. Restarting the video is starting it from the beginning. How can I either directly in the command line start from, let's say, minute 30, or alternatively jump in the mpv interface to minute 30 *without* pressing 30 times the up button (which also has issues if done too fast)? I haven't found an answer related to that issue in the man page. Is it possible at all? Also alternative suggestions for streaming are welcome.
