```ts
const orderTimestampBytes: Order<TimestampBytes> = orderUint8Array;
```

Defined in: [packages/common/src/local-first/Timestamp.ts:346](https://github.com/evoluhq/evolu/blob/49ea8ca499566aba270f8cb601e7f49aa62320f8/packages/common/src/local-first/Timestamp.ts#L346)

An [Order](https://evolu.dev/docs/api-reference/common/Order/type-aliases/Order) for [TimestampBytes](https://evolu.dev/docs/api-reference/common/local-first/Timestamp/variables/TimestampBytes).

This `Order` uses lexicographic byte order to compare serialized
[TimestampBytes](https://evolu.dev/docs/api-reference/common/local-first/Timestamp/variables/TimestampBytes) produced by [timestampToTimestampBytes](https://evolu.dev/docs/api-reference/common/local-first/Timestamp/functions/timestampToTimestampBytes). See
[orderUint8Array](https://evolu.dev/docs/api-reference/common/Order/variables/orderUint8Array) for the underlying implementation.
