Review the [AWS SiteWise Integration Guide](docId\:DNUXDqFn7nn8ALAIbL0Mq). 

## Overview

AWS SiteWise integration enables an Edge System connection with Amazon AWS IoT SiteWise.

## Supported Communication Directions

- Outbound: Publish data from Edge to AWS IoT SiteWise
- Inbound: Subscribe to data from AWS IoT SiteWise

## High-Precision Timestamps (offsetInNanos)

The AWS IoT SiteWise connector supports high-precision timestamps in the standard deviceHub payload. You can provide a timestamp object containing both `timeInSeconds` and `offsetInNanos` fields. This enables nanosecond-level precision for asset property values sent to AWS IoT SiteWise.

### Payload Format

To use high-precision timestamps, include the timestamp object in your payload:

```json
{  "datatype": "float64",  "description": "",  "deviceID": "C250EEBF-2611-47F8-B8B9-A27F084DA3D7",  "deviceName": "sim",  "metadata": {},  "registerId": "FDD88267-AABD-4118-A2EE-24E2D89CEFB5",  "success": true,  "tagName": "tag1",  "timestamp": {     "timeInSeconds": 1765387245162,    "offsetInNanos": 0  },  "value": 0}
```

where:

- `timeInSeconds` is the main timestamp in seconds (Unix epoch time).
- `offsetInNanos` (optional) specifies a nanosecond offset for higher precision. Set to `0` if not needed.

### Considerations

High-precision timestamps allow for more accurate event ordering and data analysis in time-sensitive applications. High-precision timestamps also allow for data transformation. Use Analytics to convert DeviceHub standard timestamps, enrich data, or filter records before sending to AWS IoT SiteWise.

Note the following:

- `timeInSeconds` and `offsetInNanos` both map directly to the `BatchPutAssetPropertyValue` in AWS IoT SiteWise.
- `offsetInNanos` defaults to `0` when omitted.
