Function Timestamp

Timestamp(unixSeconds: bigint): RelishTimestamp
Creates a timestamp Relish value.

Timestamps represent Unix epoch time (seconds since 1970-01-01 00:00:00 UTC) as a 64-bit signed integer. When decoded, produces a Luxon DateTime object.
Parameters
- unixSeconds: bigint
  BigInt representing seconds since Unix epoch
Returns RelishTimestamp
RelishTimestamp value
Example
```
import { Timestamp, encode } from '@grounds/core';

// Encode current time
const now = BigInt(Math.floor(Date.now() / 1000));
const timestamp = Timestamp(now);
encode(timestamp).match(
  (bytes) => console.log('Timestamp encoded:', bytes),
  (error) => console.error(error)
);
```
Remarks
Precision is seconds (no milliseconds or microseconds). For nanosecond precision, encode as a struct with separate second and nanosecond fields.
