There are some people manipulating time... Why?

The player Sakhanda manipulated the time , so I lost cause luck of time. That's not fair.

Manipulated in which way?

Yes!

Can you please explain in what way this player manipulated time?
Did the clocks keep going for some time after each move and then jump to another value?
Did time run out and then reappear as a positive number?
If that is the case, that is the effect of network lag and lichess's time compensation algorithm.

You are lagging. There is no way to manipulate the time.

Once I'm finished manipulating thyme I plan on sandbagging some saffron and checkmating some chives

If someone would move with near-light speed and you would sit on Earth and play online chess against them, how would that feel? We know that processes in a body that moves with fast speed slow down. So they would make a move, for example, for a second, but for us it would seem like a minute. Hmm, I don't think it's possible to take advantage of time if one moves with near-light speed. Probably, they'd rather lose, because their moves for people on Earth and Lichess server would be slower than for them.

But from their frame of reference we are the ones moving at near light speed, so wouldn't it be the same thing in the other direction and they have the advantage?
The answer is no.
If they are moving in a straight line the lag would grow exponentially as the game is played, and would quickly become very long.
If they were moving around a curved trajectory, on the other hand, they would have to have a very high acceleration, and that would make the difference, giving us the advantage.
They could possibly gain a small advantage by playing from space, or perhaps there is a small difference between the poles of the earth and the equator, due to rotation, but that is negligible.

A slightly easier way of manipulating time would be to trick lichess into thinking that your connection is laggy when it actually isn't, perhaps by playing on a device with an artificially slowed down connection while spectating on another device with a fast connection to get the opponent's moves earlier, but this means that you have to glance back and forth between two screens, making it difficult to concentrate on the game.

Fortunately, there does not appear to be any easy way to cheat the time control without incurring drawbacks.

Have any astronauts (i.e. ISS Space Station Crew) used LiChess to play from space? They might have valid complaints about time manipulation. (Then again, they'll likely understand the physics and not complain.)

Complaints about time manipulation are ... "out of this world."

@Kataphraktoi @Allonautilus @MrCharles Actually, as far as I understand Lichess lag compensation, there is a way to manipulate time: by artificially adding lag for all the requests to Lichess, except those of move sending. Lichess will think that the lag is large, but the player thinks quickly. This could probably be incorporated as a browser extension or at least a browser recompile and would not require any action from the user during the game. I see absolutely no theoretical way of protection against such an attack, though I dunno how easily that can be done by cheaters.
