How to set the time zone for CSV data export?

[crasch]

[Apologies if this is the wrong place for this kind of question, but I wasn't sure where else to ask.]

I have a form on form.io with two datetime picker components. You can see the form here:

https://formview.io/#/bjwhsbxofdwhpqg/elysiumferrysignup?header=1

The datetime is displayed as follows in the table displayed online:

2019-07-19 06:00 PM

However, when I export the csv file, the time is converted to this format:

2019-07-20T01:00:00.000Z

If I edit the component, I see a checkbox that says "Use Locale Settings". However, when I check the box, I get another box that says "Custom CSS fields" I've not been able to find a place to set the locale settings for a project yet.

How do I configure form.io to export the data in the first format, not the second?
How do I set the time zone?

Thanks!
