what widget can be used to select dates/times similar to Outlook calendar entries

I am creating a form for persons outside of our organization to be able to submit a request to have a deadline, event, concert, rehearsal, task, etc. to a "Master Calendar" for the organization.  

I've found a date selector but having difficulty finding something useful to select a time rate for the specified date.  

What do you recommend.

UPDATE (February 22, 2019): Direct integration with Google Calendar is available now. You can check our guide on How to Use Google Calendar to Create Events with Your Form to learn more.

You can also have a look at the announcement blog post for our Google Calendar Integration.

We have various calendar widgets that you could use. Here is the list - https://widgets.jotform.com/search/calendar

I've found a date selector but having difficulty finding something useful to select a time rate for the specified date.

Do you mean you are unable to select a time range? If it's time range you can take a look a look at the date difference widget or the Check-in Check-Out widget. You can also use the Date Picker widget twice for the start and end time.

I hope this helps.
