I had already replied on Reddit before I had seen your email here. Let 
me link the thread for further reference:

 From what I understand there was a misunderstanding about the behavior 
of the `Duration::fromSeconds()` constructor in that it would also limit 
the `$seconds` value (to `59` I assume). This is false, all of the 
following would be perfectly legal:

     Duration::fromSeconds(120); // Two minutes
     Duration::fromSeconds(86_400); // One 24-hour-day
     Duration::fromSeconds(31_556_925,
                           43_200_000); // One solar year according
                                        // to WolframAlpha.

Only the (optional) `$nanoseconds` parameter is limited in that it must 
be smaller than “1 second” to achieve the “fixed point decimal” 
semantics. The `fromNanoseconds()` constructor that only takes 
nanoseconds will allow overflow into larger units as will all the other 
constructors. The injectivity is on a per-constructor basis.

You can also check the proof-of-concept implementation, while it is 
non-authoritative, it correctly implements the proposed overflow and 
range-checking semantics.
