How To Make The Timecode (Clock) Accurate

Heres how I make the clock in the BMPCC4K or 6K or 6K pro as accurate as possible, First start by plugging the camera into AC power, Second Remove the battery and restart the camera (whilst on AC), Thrid go into the setup menu and select date and time and use a website like time.is to sync time then press update. Your time should be accurate now.

Ramble:

I have no idea why the engineers at blackmagic decided to not have a seconds slider in the menu this would make setting time so much more consistent and accurate, I'm sure people who sync audio and film alot in a day would agree this is a massive oversight on blackmagics behalf, This isn't a difficult issue to address all it needs is an update. Why not just have camera connect to the internet to fetch the most accurate time?.
