Struct Iso8601TimeNoSp 

pub struct Iso8601TimeNoSp(pub SystemTime);

A wall-clock time, encoded in ISO8601 format without an intervening space.

This represents a specific UTC instant (ie an instant in global civil time). But it may not be able to represent leap seconds.

The timezone is not included in the string representation; +0000 is implicit.

(Example: “2020-10-09T17:38:12”)

Methods from Deref<Target = SystemTime>

pub const UNIX_EPOCH: SystemTime = UNIX_EPOCH

pub fn duration_since( &self, earlier: SystemTime, ) -> Result<Duration, SystemTimeError>

Available on crate feature parse2 only.

Returns the amount of time elapsed from an earlier point in time.

This function may fail because measurements taken earlier are not guaranteed to always be before later measurements (due to anomalies such as the system clock being adjusted either forwards or backwards). Instant can be used to measure elapsed time without this risk of failure.

If successful, Ok(Duration) is returned where the duration represents the amount of time elapsed from the specified measurement to this one.

Returns an Err if earlier is later than self, and the error contains how far from self the time is.

Examples

use std::time::SystemTime;

let sys_time = SystemTime::now();
let new_sys_time = SystemTime::now();
let difference = new_sys_time.duration_since(sys_time)
    .expect("Clock may have gone backwards");
println!("{difference:?}");

pub fn elapsed(&self) -> Result<Duration, SystemTimeError>

Available on crate feature parse2 only.

Returns the difference from this system time to the current clock time.

This function may fail as the underlying system clock is susceptible to drift and updates (e.g., the system clock could go backwards), so this function might not always succeed. If successful, Ok(Duration) is returned where the duration represents the amount of time elapsed from this time measurement to the current time.

To measure elapsed time reliably, use Instant instead.

Returns an Err if self is later than the current system time, and the error contains how far from the current system time self is.

Examples

use std::thread::sleep;
use std::time::{Duration, SystemTime};

let sys_time = SystemTime::now();
let one_sec = Duration::from_secs(1);
sleep(one_sec);
assert!(sys_time.elapsed().unwrap() >= one_sec);

pub fn checked_add(&self, duration: Duration) -> Option<SystemTime>

Available on crate feature parse2 only.

Returns Some(t) where t is the time self + duration if t can be represented as SystemTime (which means it’s inside the bounds of the underlying data structure), None otherwise.

pub fn checked_sub(&self, duration: Duration) -> Option<SystemTime>

Available on crate feature parse2 only.

Returns Some(t) where t is the time self - duration if t can be represented as SystemTime (which means it’s inside the bounds of the underlying data structure), None otherwise.
