Possibility to save exact move times using player's computer.

Hello!
As we already discussed, it's impossible to save move times unrounded, because it takes a lot of memory space.
But there could be some decision.
After every game the exact move times are available for some amount of time. And a player can save it on his computer. So, later he could connect the file with move times on his computer with the game on Lichess. And we could watch all games, we want as they exactly were played.
And we could analyse our time mistakes, that is very important fast games, and even for games of any duration.

for fast games*

Some places to put this in might be, when you mouse over the move number (in the move listing area) it would show you the local time stamps for the pair of moves played. And then perhaps in the analysis board, the server times would be made available.

Another idea is that in the auto play back area, there could be a x2 (times two), or x4, and x8 play back mode. That should cover most blitz and standard times for reasonable playback speed, perhaps indicated with an icon that it utilizes server timestamps.
