Filter SharePoint List Views by Date and Time

By default if you do filtering of views by DateTime field via web, it will only filter the views by date, not including time. In order to include time, you need to modify the view using SharePoint Designer. Here are the steps on how to do it.

1. Open the site in which the list or document library resides using Microsoft Office SharePoint Designer.
2. Locate the list or document library and open the .aspx file associated with the view (e.g. “AllItems.aspx”)
3. Click the Code tab and locate the CAML query associated with the filter (search on the name of your DateTime field, e.g. "StartDateTime"). 
4. Edit the CAML query to include the IncludeTimeValue attribute (IncludeTimeValue="True"). Please note that you need to include spaces exactly as shown in the sample below: 

            <Gt>
             <FieldRef Name="StartDateTime"/>
             <Value Type="DateTime" IncludeTimeValue="True">
              <Today/>
             </Value>
