I have a data where there is a column named "Start Date" of String data type

I need to create 2 separate columns based on that record.
- 11-01-2022 – This should be showing as “Last Backup happened on 11th January 2022” in a separate column.
I did it, kindly give me your opinion that the process is correct or not.

- How can I convert the hh:mm:ss to AM/PM? For example -
02:00 will show – Backup initiated on 2 AM
00:11:05 will show – Backup initiated on 12:11 AM
09:00:14 will show – Backup initiated on 9 PM
00:00:00 will show - Backup initiated on 12 AM
This should be showing in another column named - "Backup Schedule Time"
Please help
