Is there a difference between Self Hosted Mautic and Mautic Cloud?

Your software
My Mautic version is: 2.16.2
My PHP version is: 7.1.33

Your problem
When looking at the send options for segmented email I do not see the option to send at a particular date/time.

Is this only available to Mautic cloud?
And are there any other differences between the two versions?

In the documentation here ->
It mentions that you can schedule an email to be sent at a particular date/time.

However in my Self Hosted version it does not allow the setting of a date/time:

Enter the number of emails to send per batch then click Send to start the process.
