Working with Dates and Times in Rust Learn how to handle dates and times in Rust using the chrono crate. This guide covers basic operations, timezone handling, and formatting. You'll see practical examples for common datetime tasks. Core DateTime Operations Use these essential datetime functions in Rust: - Parse strings into dates with `NaiveDateTime::parse_from_str` - Get current time using `Utc::now()` - Add days safely with `checked_add_signed` - Compare dates using standard operators like > and == Advanced Timezone Handling Manage timezones properly in your Rust code: - Convert between timezones with `chrono-tz` - Parse ISO 8601 strings with timezone info - Handle daylight saving time changes correctly - Work with leap seconds in timestamp conversions Formatting and Parsing Control how dates appear as strings: - Customize formats using strftime patterns - Parse different date string formats - Convert between strings and dates without losing data - Optimize parsing for better performance Error Handling and Best Practices Write reliable datetime code: - Validate all datetime inputs - Handle edge cases like invalid dates - Store datetimes properly in databases - Test timezone changes thoroughly Real-world Applications See Rust datetime code in action: - Build timezone tools - Process log files with precise timestamps - Create calendar systems - Implement cache expiration Performance Benchmarks See how Rust datetime operations compare: - Measure parsing speed - Test timezone conversion costs - Compare with other languages - Check memory usage
