# Timezone configuration

> Set the timezone that anchors Building BI date and time filters so relative ranges resolve in local time.

Set a timezone when you [create a dashboard](/products/building-bi/dashboards#create-a-dashboard). Without one, date and time filters resolve against UTC, so buildings in other zones can miss part of ranges like "today."

| Scope                               | Default            | Editable                        |
| ----------------------------------- | ------------------ | ------------------------------- |
| Dashboard (portfolio)               | UTC                | Create dialog; edit mode        |
| Dashboard (building)                | Building timezone  | Edit mode                       |
| Filter (dashboard, page, or widget) | Dashboard timezone | Edit mode only                  |
| Slicer (date/time columns)          | Dashboard timezone | Optional override on the slicer |
| Dashboard template use (portfolio)  | UTC if omitted     | Prompted on use                 |

You cannot change a date/time filter timezone in view mode.
