Follow these steps to divide field into multiple fields. I have used country to demonstrate you the working of code.
1. Create calculated field as first-name and last name by using split function().
Similarly do for first name by writing 1 instead of 2.
Here index 1 indicates the first word or string before split and so on.
2. Now add these 2 column next to actual field to see the date and time separately.
Hope this helps you.
