The remaining time in a correspondence game is usually displayed in hours or days, provided that it is greater than 24h.
In particular, the number of minutes is not indicated.
This is fine, but I think it would be much better if the time was rounded rather than truncated.
For instance, I had exactly 48h remaining on my clock in a game with “Fisher: increments by 1 day per move up to a maximum of 2 days”; and my opponent played their move a few seconds ago. Now my time is displayed as “47h”, both in the “Active games” category and on the game page itself; and there is no way to see that it’s actually 47h59min50s, which is extremely close to 48h, and pretty far from 47h.
So this is my suggestion:
When the remaining time is displayed in hours or days, please show the rounded time rather than the truncated time.
