Telegram has those floating dates bubbles. On paper it sounds like a great idea: dates don’t eat up chat space, they are always on screen so you know exactly when the message was written, even when it’s very long or there are million other messages sent the same day.
In practice you almost never care about exact date, but they eat lots of screen space and don’t let you read your messages: the actual content you care about. Good UI solution applied to the wrong problem.
