title: Get Azure resource group creation time
body: <p><strong>Intent</strong>: Know when a resource group was created for the first time.  The client organization wants to report and act on resource group creation timestamps. This will be used in automation scripts.</p>
  
  <p>Unfortunately there is no <em>creation timestamp</em> property on resource groups.  Using <code>Get-AzureRmResourceGroup</code> returns objects like this:</p>
  
  <pre><code>ResourceGroupName : eastus2-something-rg
  Location          : eastus2
  ProvisioningState : Succeeded
  Tags              :
  ResourceId        : /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/eastus2-something-rg
  </code></pre>
  
  <p>This feature has <a href="https://feedback.azure.com/forums/223579-azure-portal/suggestions/32424859-creation-date-as-a-first-order-property-for-all-re" rel="noreferrer">been requested</a>, but doesn't appear to have many votes.</p>
  
  <p>How do I retrieve the creation timestamp for a resource group?</p>
