I found one similar solution that almost does what I want.  

[DateTimePicker System.xml](https://magento.stackexchange.com/questions/202487/date-field-system-xml?answertab=active#tab-top) 

I have implemented its code and was able to display a **`DateTime Picker`** in my admin configuration. However, I would like to implement a **`Time Range Picker`** but I don't need a UI component way of implementing it.
