Button to create a date and time

To add on to Mark's response, if you want the ability to clock in and out, set up an other formula URL for clocking out. Put the buttons right next to each other in the form. Then, in the form rules, set up a rule that says if the clock in time is empty, show the clock in formula URL and hide the clock out formula URL. Depending on your use case, you may want to have another rule that hides both buttons if both the clock in and clock out time are already filled in. That way, the user will only see the button that she needs to see.
