--- Comment #2 from Jonathan M Davis <[email protected]> --- toString does currently call toSimpleString, but the intention is that if you actually care about the format of the string, you don't use toString. Instead, you use a function like toSimpleString or toISOExtString that's explicit about the format. toString is just intended to convert the type to a user-friendly string, not for specific formatting. --
