I know that Marketo calculates time zone based on a person's City, State, Country, or Zip Code. So I'm wondering if we can alter this to base it off of a custom field we use called Country/Nation instead of Country? I don't see anywhere to adjust this. Also curious if we can customize it to only base it on Country/Nation field and not the other fields.
Thanks in advance!
I am not aware of this customization. Suggest you leverage Country/Nation to push the value to the standard field.
Mailchimp uses the click time and IP matching to decide on the person's time zone. I do not believe Marketo does this yet.
