Crate: chrono

Role in Pour

Used for generating timestamps in file names (e.g., 2026-03-30_1205_V60.md) and daily note paths (e.g., 2026-03-30.md).

Getting Current Time

use chrono::Local;

let now = Local::now();

Formatting with Strftime

// Daily note path: "2026-03-30.md"
let date_str = now.format("%Y-%m-%d").to_string();

// Coffee log filename: "2026-03-30_1205_Brew.md"
let timestamp = now.format("%Y-%m-%d_%H%M").to_string();

// Full timestamp for entries: "14:32"
let time_str = now.format("%H:%M").to_string();

Common format specifiers:

Specifier Meaning Example
%Y 4-digit year 2026
%m Month (01-12) 03
%d Day (01-31) 30
%H Hour 24h (00-23) 14
%M Minute (00-59) 05
%S Second (00-59) 32
%A Weekday name Monday
%B Month name March

Parsing Dates

use chrono::NaiveDate;

let date = NaiveDate::parse_from_str("2026-03-30", "%Y-%m-%d")?;
