As it turns out, numbers from 0 to 59 separated by colons are sexagesimal (base 60) number literals. This arcane feature was present in yaml 1.1, but silently removed from yaml 1.2, so the list element will parse as 1342 or "22:22" depending on which version your parser uses. Although yaml 1.2 is more than 10 years old by now, you would be mistaken to think that it is widely supported: the latest version libyaml at the time of writing (which is used among others by PyYAML) implements yaml 1.1 and parses 22:22 as 1342.

The change from yaml 1.2.1 to 1.2.2 on the other hand, was a multi-year effort by a team of experts
