What is the problem?

I am playing a correspondence game with 1 day per turn. I have the game open and do not leave the game for the following turns. Timestamps in this scenario are for simplicity.

Say I am white, I have just played, and I am waiting for black to play. Black's clock reaches 23:55 and they play their turn. The expected behavior is that black's clock should reset to One day, however it will sometimes keep decrementing. I then play my (white's) turn immediately. Black's clock now reads 23:54, when it should read 23:59. If I leave the game and come back, the clocks are correct.

This appears to occur intermittently, and affects both black's and white's clocks at any given time.

I only really play correspondence, so I'm not sure how this bug manifests in other game types.

Steps to reproduce the bug

1. Create a correspondence game with 1 day per turn
2. Start as white and play your turn.
3. Black's clock should now read 23:59. White's clock should read One day
4. Keep the game open
5. Allow some time (a couple minutes) to elapse before black plays their turn
6. Repeat step 5 for each player until clocks are incorrect.

Additional information

Screenshots are consecutive moves in a real game. Clocks don't reset to One day.

Move 27	Move 28

If I leave the game screen and come back, the clocks are correct:
