[RFC] Duration class

Tim Düsterhus and Derick Rethans have proposed a new Time\Duration class for PHP 8.6 to represent stopwatch-style durations, primarily to improve the developer experience for timeout-related APIs like the new Polling API. The RFC is intentionally minimal, using a seconds + nanoseconds internal representation (similar to Rust's and Java's Duration). Community discussion covers design questions including: why the highest constructor unit is hours, the absence of an ISO 8601 serialization method (deferred to PHP 8.7), omission of floating-point total methods due to precision concerns, namespace choice (Time vs DateTime), and whether to use add/sub methods or a single variadic sum method. The authors also explain why they chose not to adopt the JavaScript Temporal API or the temporal_rs Rust library, citing PHP's semantic closeness to Java and the complexity of integrating Rust into the Zend Engine.
