Expand description

A trait representing a clock with timezone support.

This trait extends Clock to provide timezone information and methods to get the current local time in the clock’s timezone.

§Examples

use prism3_clock::{Clock, ZonedClock, SystemClock, Zoned};
use chrono_tz::Asia::Shanghai;

let clock = Zoned::new(SystemClock::new(), Shanghai);
let local = clock.local_time();
println!("Local time in Shanghai: {}", local);

Required Methods§

Source

fn timezone(&self) -> Tz

Returns the timezone of this clock.

§Returns

The timezone associated with this clock.

§Examples
use prism3_clock::{ZonedClock, SystemClock, Zoned};
use chrono_tz::Asia::Shanghai;

let clock = Zoned::new(SystemClock::new(), Shanghai);
assert_eq!(clock.timezone(), Shanghai);

Provided Methods§

Source

fn local_time(&self) -> DateTime<Tz>

Returns the current local time in this clock’s timezone.

This method has a default implementation that converts the UTC time from time() to the local time using the clock’s timezone.

§Returns

The current local time as a DateTime<Tz> object.

§Examples
use prism3_clock::{ZonedClock, SystemClock, Zoned};
use chrono_tz::Asia::Shanghai;

let clock = Zoned::new(SystemClock::new(), Shanghai);
let local = clock.local_time();
println!("Local time: {}", local);
