pchickey opened PR #7358 from bytecodealliance:pch/monotonic-clock-duration to bytecodealliance:main:

Implement the interface change submitted upstream as https://github.com/WebAssembly/wasi-clocks/pull/53

We are introducing a duration type because it has a distinct meaning
from instant: an instant can only be compared to other instants
from the exact same monotonic-clock, whereas a duration represents
a duration of time which can be compared to any other duration of time.

The duration type is motivated, in part, by a desire to reuse it to
specify durations such as timeouts in other WASI proposals.

Instead of taking a boolean specifying whether the u64 is an absolute or
relative time, subscribe-instant takes an instant type and
subscribe-duration takes a duration type.

Could this method perhaps delegate to subscribe_duration or a similar helper once it calculates the relative desired Duration? Or alternatively would it be possible to directly convert between when and a tokio::time::Instant?

It basically felt a bit odf that the Never case was handled below but not here

Thanks, I thought that over again and factored it out into a helper function.
