Nanosecond-resolution start reading, as returned by `process.hrtime.bigint()`.

**Signature:**

```typescript
start: bigint | number;
```

## Remarks

A `number` is accepted but must be an integral nanosecond count: a non-integer throws a `RangeError`, and a millisecond timestamp such as `Date.now()` produces a meaningless duration.
