Sometimes I really feel good about myself. Imagine that a body of knowledgeable people intentionally created this:
> There are several methods provided by #JavaScript Date that can be used to convert numeric date information into a properly-formatted string. For example, the Date.toISOString() method returns the date/time in UTC with the suffix "Z" denoting that timezone; removing the "Z" would provide a value in the format expected by a datetime-local input.
