Dates in exported CSV file vary in format

Dates in exported CSV file vary in format

When I generate a simple custom report and view it in Zoho Support, the dates show in the format of dd/mm/yyyy hh:mm AM.

But when I export in CSV format, I get a mixture of date formats as shown in the included screenshot.  



This makes it impossible to import the data into Zoho Reports, which I am trying out.

Is there some setting I may be missing or something else I may be doing incorrectly?
