<p>When you select time dimensions in the Group By menu, you'll see a list of available time granularities. The lowest granularity is selected by default. Metric time is the default time dimension for grouping your metrics.</p>

:::info 
Note: [Custom time granularities](/docs/build/metricflow-time-spine#add-custom-granularities) (like fiscal year) aren't currently supported or accessible in this integration. Only [standard granularities](/docs/build/dimensions?dimension=time_gran#time) (like day, week, month, and so on) are available. If you'd like to access custom granularities, consider using the [Semantic Layer APIs](/docs/dbt-cloud-apis/sl-api-overview).
