Struct UnixTimestamp 

pub struct UnixTimestamp(/* private fields */);

A Unix timestamp representing seconds since the Unix epoch (1970-01-01T00:00:00Z).

This type is used throughout the x402 protocol for time-bounded payment authorizations:

• validAfter: The earliest time a payment authorization can be executed
• validBefore: The latest time a payment authorization remains valid

Serialization

Serialized as a stringified integer to avoid loss of precision in JSON, since JavaScript’s Number type cannot safely represent all 64-bit integers.

"1699999999"

Example

use x402_types::timestamp::UnixTimestamp;

// Create a timestamp for "now"
let now = UnixTimestamp::now();

// Create a timestamp 1 hour in the future
let expires = now + 3600;

// Create from a specific value
let specific = UnixTimestamp::from_secs(1699999999);
assert_eq!(specific.as_secs(), 1699999999);

Implementations

impl UnixTimestamp

pub fn from_secs(secs: u64) -> Self

Creates a new UnixTimestamp from a raw seconds value.

Example

use x402_types::timestamp::UnixTimestamp;

let ts = UnixTimestamp::from_secs(1699999999);
assert_eq!(ts.as_secs(), 1699999999);

pub fn now() -> Self

Returns the current system time as a UnixTimestamp.

Panics

Panics if the system clock is set to a time before the Unix epoch, which should never happen on properly configured systems.

Example

use x402_types::timestamp::UnixTimestamp;

let now = UnixTimestamp::now();
// Timestamp should be after year 2020
assert!(now.as_secs() > 1577836800);

pub fn as_secs(&self) -> u64

Returns the timestamp as raw seconds since the Unix epoch.

Example

use x402_types::timestamp::UnixTimestamp;

let ts = UnixTimestamp::from_secs(1699999999);
assert_eq!(ts.as_secs(), 1699999999);
