What I’ve already tried:

Removed Cargo.lock and re-ran the build — issue persists.
Tried pinning arrow and all sub-crates (e.g., arrow-arith, arrow-select, arrow-string) to 54.2.1 using [patch.crates-io] in Cargo.toml.
However, during build, arrow-arith = 49.0.0 still gets pulled, leading to the same quarter() ambiguity.
Ran cargo tree -i arrow-arith and confirmed old dependency is being resolved indirectly.

Worked around it now by:

1. Changing the chrono dependency to 0.4.31 specifically, by changing in Cargo.toml, from:

chrono = "0.4"

... to:

chrono = "=0.4.31"

2. Running cargo clean
3. Running cargo update
4. Then building again with:

cargo build --release

Got a couple of warnings, but the build went through.
