offset

The offset for the tumbling window. The offset parameter accepts the following:

  • The offset time.For example, if you specify 18h for offset and 1d for interval, IoT SiteWise aggregates data in one of the following ways:

    • If you create the metric before or at 6 PM (UTC), you get the first aggregation result at 6 PM (UTC) on the day when you create the metric.

    • If you create the metric after 6 PM (UTC), you get the first aggregation result at 6 PM (UTC) the next day.

  • The ISO 8601 format.For example, if you specify PT18H for offset and 1d for interval, IoT SiteWise aggregates data in one of the following ways:

    • If you create the metric before or at 6 PM (UTC), you get the first aggregation result at 6 PM (UTC) on the day when you create the metric.

    • If you create the metric after 6 PM (UTC), you get the first aggregation result at 6 PM (UTC) the next day.

  • The 24-hour clock.For example, if you specify 00:03:00 for offset, 5m for interval, and you create the metric at 2 PM (UTC), you get the first aggregation result at 2:03 PM (UTC). You get the second aggregation result at 2:08 PM (UTC).

  • The offset time zone.For example, if you specify 2021-07-23T18:00-08 for offset and 1d for interval, IoT SiteWise aggregates data in one of the following ways:

    • If you create the metric before or at 6 PM (PST), you get the first aggregation result at 6 PM (PST) on the day when you create the metric.

    • If you create the metric after 6 PM (PST), you get the first aggregation result at 6 PM (PST) the next day.
