Providing guidance to your customers as to the grain of time they have applied to a given set of data when using a filter can be helpful guider text within your dashboards. Being able to do data transformation to present this information in a consistent and more easily readable way, while also maintaining the dynamic values, can be especially helpful!
Enter CSS 
magic
By adding the mustache syntax to access field variables within a data property in a html element, CSS can then be used to append a value to the same html element to create a dynamic value that can be included in your dashboard.
In the example code below, I added a data element to a tag and set the data element to the selected value from the filter ({{filters.table.field.summary}}). Within the CSS for the h3 element for each time grain value, I set a value to be appended “::after” to the h3 element.
This shows in the tile as a dynamic value for “Time Grain Selected:” and then the grain of time (minute, hour, day, week, month, year) is appended or the full string of the date filter is returned as a fallback.
h/t to @sarah on our Design team for being a markdown magician and helping build this out!
One caution: this won’t come through in deliveries and alerts given the CSS Magic to make it happen!
