+We're happy to announce that Sumo Logic now enables you to remotely update the collector timezone for OpenTelemetry collectors through the UI in the OpenTelemetry collector edit flow. You can select the timezone of your choice while editing the collector. If you do not make a selection, the timezone will be set to `(UTC) Etc/UTC` by default.

-    1. **Select Timezone**. Define the geographic location (time zone) to use while parsing a timestamp that does not include a time zone. The available locations depend on the local IANA Time Zone database. For example, `America/New_York`. For more examples, refer to the [List of tz database time zones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones).

     1. **Format**. Specify the exact layout of the timestamp to be parsed. For example, `- %Y-%m-%dT%H:%M:%S.%LZ`. To learn more about the formatting rules, refer to [this guide](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/internal/coreinternal/timeutils/internal/ctimefmt/ctimefmt.go#L68).
     1. **Timestamp locator**. Use a [Go regular expression](https://github.com/google/re2/wiki/Syntax) to match the timestamp in your logs. Ensure the regular expression includes a named capture group called `timestamp_field`.<br/><img src={useBaseUrl('img/send-data/st-timestamp-parsing.png')} alt="Screenshot of the Timestamp parsing section for logs in Sumo Logic, focusing on the timestamp format settings" style={{border: '1px solid gray'}} width="400" />
