+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).
