Clock of opponent always stops counting down correctly!

I'm new and I've been enjoying the last few days here at chess.com. Today, for the first time, I experienced an unusual loss of time from my side every time it was my turn. I did not even play the time I had or approximately close to the time I was supposed to have (e.g. I made rapid movements under a second, but still lost about 10 seconds for each move but not my opponent.). I don't think that was lag and I'm connected through fiber that runs at 1gb up and down. 

By the way, that happened on every game I played today. I've played a couple of days and it only happened today on every game to be clear.

I've literally never had this issue. but I do know that certain game types will add time if you make a move in a certain time period.

You can see the timestamps in your archive on the website. It won't tell you why moves took that amount of time but it will show you that all the time was accounted for.

The quality of your local connection is just a small part in the time it takes for the data to transit between the client and the server process.

I agree . i lost so many games this way.

My guess is the server time compensation has bugs in it, people may be able to alter their device timing, or disconnecting and reconnecting affects server calculations of time lags and network speed. 

I'll be playing lightning fast and mid game I'll see I have 40 secs left and my opponent has 2:20 mins in a 3 mins game, it weakens, I've submitted to assuming I have 1 min to checkmate in any 3 mins game or lose on time.

Anyway it is a real issue and so annoying. I also noticed that playing via browser seem to have more accuracy in timing than playing via app, but my browser makes play frustratingly slow, as everything seem to drag. 

Lastly if chess.com can make the option of having my clock positioned on top so my hands doesn't  block it and I can see it through the game. Rather than removing my hands to check on the clock periodically.

I just experienced on a bullet game, a lot of bugs.  On my screen , I played twice as fast as my adversary, and the clock said the reverse. At a moment, he gain time  : he wins a few seconds. 

Fast games are fun, but this time issue are really painful. 

The opponent's time begins to increase when he loses instead of decreasing at the end of the game. New cheat from hackers?

All your recent games gave been 2|1 games which means one second is added to each player's clock after their moves. With premoves the clock will increase.

Same to me i start boring this ,i have lost about 10 games bullet everyday,it's stupid problem

I believe this may be a coding error.. Since the moves are done so fast, the clock doesn't account for time that is quicker than .01 or .001 seconds and Java will round up in the clocks programming.  For instance, if your clock stops at 10.009, the code rounds up to 10.010, instead of continuing down to lower decimal because that particular for loop's double should have more zeroes. I could be wrong, but that would be a easy thing to check and fix right away. I've noticed it too and I believe this may be the coding on the clock. If I worked for chess.com I'd check the Java. It's lost me a few games too and it's not lag.

Most moves are going to take longer than the premove minimum time of 0.1 seconds, but there is the possibilty of moves being faster and people have posted moves in the past that happened faster, though it's uncommon.

What is your suggestion for people who are playing bullet and constantly have this issue? It makes it hard to manage your time if you have no idea whether your opponents clock is going to stop at 10 seconds and take 20 seconds on your end to run down to 0 seconds. Even in bullet there are times to move fast and times to think a little longer. Clock management is a fun and integral part of bullet and this makes it impossible to do so.
