# Module std::time 1.3.0[−][src]

Temporal quantification.

Example:

    use std::time::Duration;

    let five_seconds = Duration::new(5, 0);
    // both declarations are equivalent
    assert_eq!(Duration::new(5, 0), Duration::from_secs(5));

Run

## Structs

Duration | A `Duration` type to represent a span of time, typically used for system timeouts.
Instant | A measurement of a monotonically nondecreasing clock. Opaque and useful only with `Duration`.
SystemTime | A measurement of the system clock, useful for talking to external entities like the file system or other processes.
SystemTimeError | An error returned from the `duration_since` and `elapsed` methods on `SystemTime`, used to learn how far in the opposite direction a system time lies.

## Constants

UNIX_EPOCH | An anchor in time which can be used to create new `SystemTime` instances or learn about where in time a `SystemTime` lies.
