Got some clarification from Soares about this.

I wonder if we'd be more interested in getting tendermint::Time here?
That would also get rid of a public dependency on time.

Outside of ics07, we are not supposed to depend on Tendermint-specific code but I guess we can make an exception for the Time struct since it's general purpose?

In my mad scientist's secret world assimilation plan, we'll migrate to a common domain types crate that will provide idiomatic Rust support for Google's well-known protobuf types, and tendermint::Time will be morphed into one of the types from that yet unpublished crate. Until then, it could be whatever seems most practical at the moment.

Should we not perhaps implement a now_utc() method for the Time struct to avoid directly importing dependencies from the time crate? I'd generally prefer to use interfaces that hide their underlying implementations as far as possible, as it reduces entanglement.

The trouble with now_utc is, it requires std. So I assume it can't be part of Tendermint's core API without an std feature gate, too.

Yeah I can look into providing that mechanism. It's probably preferable to avoid mixing newtypes and the types they're supposed to wrap.

We'd still want to provide the TryFrom/Into conversions from/to OffsetDateTime for convenience, and time is not an optional dependency at the moment (though it could be after redoing the internal representation of Time per ADR-010).
