Function RTimestamp

RTimestamp(): TRTimestamp
Creates a schema for Unix timestamps as Luxon DateTime objects.

Timestamps encode as seconds since Unix epoch (1970-01-01 00:00:00 UTC) in 64-bit little-endian format. Decoding produces a Luxon DateTime object for convenient timezone and formatting operations.

Returns TRTimestamp
A Relish schema for timestamp values
Example
```
import { RTimestamp, createCodec } from '@grounds/schema';
import { DateTime } from 'luxon';

const codec = createCodec(RTimestamp());
const now = DateTime.now().toUTC();

codec.encode(now).match(
  (bytes) => console.log('Timestamp encoded:', bytes),
  (error) => console.error(error)
);
```
Remarks
Requires Luxon library. Returned DateTime values are always in UTC. Precision is seconds (no milliseconds or microseconds).
