Timezone is different in Zapier

Also the timezones are not matching, I am not sure what time zone Jotform is displaying as the Expected Delivery Date field in the jotform displays different date on basecamp3. The time zones on basecamp and zapier is set correctly

The timezone is based on the one you have set on your account's Settings page.

Meanwhile, I just tested this and was not able to see any time difference. You can see it in action on my screencast below.

If you are getting a different value, please share the submission ID, then a screenshot of the data in your Zapier.
