When choosing Time at Depth for a deco stop, it would be useful to show both Time to Zero Ceiling, and also at what times does the ceiling change to a value that would allow a new standard gas to be breathed.
For example, if your on a deco stop at 10m, it's really useful to know how long you need to stay there until the ceiling hits 6m. Because 6m is the depth you can switch to 100% oxygen.
Same could be true of other standard gases for deeper stops.
Could show a list of key times. For example, imagine we are at a 55m deco stop:
22 mins - Ceiling = 40m - Air
32 mins - Ceiling = 33m - Nitrox 32
2 h 17 m - Ceiling = 6m - Oxygen
17 h 51 m - Ceiling = 0m
