customize changelog date format?

Instead of DD/MM/YYYY, I'd like to use YYYY-MM-DD. I don't see an option for that.

Start by tracing how this Node module formats dates when generating changelogs from releases, issues, or commits. Identify the existing DD/MM/YYYY formatting path and any related tests or documentation; done means users can select YYYY-MM-DD without changing the default format.
