Create a dynamic date and time layer(s) to your graphics.
The Date/Time element allows you to add a dynamic layer to your graphics. A layer that will automatically update with custom-formatted date and time elements.
To get started, insert a Date/Time widget into your graphic. Click on the layer in your graphic to open all of the individual customization options.
Within the right sidebar of your screen you can customize the size and placement, font and style, text shadow, and animation. The customization options are primarily the same as any other text layer in your graphic (you can find a full breakdown of each customization option here); the big difference with Date/Time is the option to customize the display format.
You can choose from 11 built-in display options in the dropdown menu, or check the 'custom format' box if you need something more specific.
You can see all of the options available in this formatting documentation. Select the 'unit' you want to use, and enter the 'pattern' in the Tagboard graphics builder. Once you're done with your graphic template, you're ready to go live!
