It's very counter-intuitive to me that 22:22 would need to be a quoted string, since functionally it's a K-V-pair. YAML itself even uses : in the Dict syntax!
The fact that it is effectively the dict syntax is precisely what makes it intuitive to me that it should be quoted if it’s going to be a a value. I admit the sexagesimal parsing is not the result I expected but I would have certainly expected something odd to happen given that the value includes a “:” character.
It's a key pair in whatever thing reads the YAML and then assign some meaning to that string. In YAML you need to put a space between the semi-colon and the value.
