vba - Refresh entire Excel workbook (all data connections and calculations) every 15 minutes?

Question

I have the following macro to refresh my workbook. This is the same as clicking on the refresh all button.

Is there a time element I can add to this code to refresh all data connections and all calculations on all the worksheets in my workbook every 15 minutes?

The workbook has cells pulling data from SharePoint list items and contain typical formula calculations as well.

Sub Workbook_RefreshAll()
ActiveWorkbook.RefreshAll
End Sub

You can use the Application.OnTime method to schedule a macro to be run in the future: https://msdn.microsoft.com/en-us/library/office/ff196165.aspx

Yet, this is a one time event only. To make it recursive, you'll have to include in that macro (yet again) another Application.OnTime to ensure a calling "every 15 minutes".
