RISC-V: Upgrade 'time' to make it compile with Rust 1.80+

Closes RV-270

What

Upgrade the time crate in places where we intend to upgrade Rust beyond 1.80.

Why

error[E0282]: type annotations needed for `Box<_>`
  --> /Users/ole/.cargo/registry/src/index.crates.io-6f17d22bba15001f/time-0.3.30/src/format_description/parse/mod.
rs:83:9
   |
83 |     let items = format_items
   |         ^^^^^
...
86 |     Ok(items.into())
   |              ---- type must be known at this point
   |
   = note: this is an inference error on crate `time` caused by an API change in Rust 1.80.0; update `time` to vers
ion `>=0.3.35` by calling `cargo update`

Upgrading addresses the above error when using Rust 1.80.0.
