alpaca-time

alpaca-time provides New York time and US trading-calendar semantics for the alpaca-rust workspace.

Core modules:

• clock
• calendar
• session
• expiration
• range
• display

Use this crate when you need:

• canonical YYYY-MM-DD and YYYY-MM-DD HH:MM:SS parsing and formatting
• RFC3339 UTC to New York session/date normalization
• trading-day and market-session checks
• expiration-date math shared across the Rust workspace

This crate intentionally does not include:

• Alpaca HTTP clients
• option contracts, pricing, or payoff math
• cache orchestration or application scheduling

An optional workspace TypeScript companion exists under packages/alpaca-time, but the published system surface is the Rust crate.

See docs/reference/alpaca-time.md and https://docs.rs/alpaca-time for the full reference.
