Hi Paul
I don't think I've seen your name on the list before. If this indeed
your first email here: Welcome and thank you for contributing!

For reference, brick/date-time's Duration class also allows seconds to
be negative instead of storing a separate flag:
Note that brick/date-time is as per the README (very) closely modeled
after Java’s implementation, except for necessary differences to fit the
API in PHP:
This component follows an important part of the JSR 310 (Date and Time
API) specification from Java. Don't expect an exact match of class and
method names though, as a number of differences exist for technical or
practical reasons.
So taking inspiration from that implementation is effectively taking
inspiration from Java’s implementation.
The nanoseconds are always non-negative, so a duration of negative
half a second would be stored as -1 seconds and 500,000,000
nanoseconds.
Yes, this matches Java’s implementation. I've explained in
https://news-web.php.net/php.internals/131466, why I don’t consider this
representation to be intuitive or easy to use.
