Bounds of the signed 64-bit integers that hold Roboto's nanosecond timestamps, timeline offsets, and row positions.

Roboto cannot store a nanosecond timestamp, timeline offset, or row position outside `[INT64_MIN, INT64_MAX]`. Many fields accept only part of this range; a file's timeline offset, for example, must not be negative.

## Module Contents

### INT64_MAX

```python
roboto.int64.INT64_MAX = 9223372036854775807
```

`from roboto.int64 import INT64_MAX`

[Source](https://github.com/roboto-ai/roboto-python-sdk/blob/main/src/roboto/int64.py#L17-L17)

The largest value a signed 64-bit integer holds. As nanoseconds since the Unix epoch, it is the instant 2262-04-11 23:47:16.854775807 UTC.

### INT64_MIN

```python
roboto.int64.INT64_MIN = -9223372036854775808
```

`from roboto.int64 import INT64_MIN`

[Source](https://github.com/roboto-ai/roboto-python-sdk/blob/main/src/roboto/int64.py#L13-L13)

The smallest value a signed 64-bit integer holds. As nanoseconds since the Unix epoch, it is the instant 1677-09-21 00:12:43.145224192 UTC.
