title: How to create time input field in PySimpleGUI
body: <p>I am trying to create a GUI in Python using PySimpleGUI to log my work hours. I am writing the data to an Excel file. So far, everything is working the way it should.</p>
  <p>What I can't figure out is how to create a time input field. I thought something similar to how the CalendarButton works would be possible, only that one is prompted with a field to select the time, not a date. Is this possible?</p>
  <p>Another thing that came to my mind was a field with those up and down arrows on the side. I have no idea what they are called, so I was not even able to find out, if and how they are available within PySimpleGUI. So, what are they called?</p>
  <p>What I am trying to avoid is to have to manually type the colon (:) between the digits. I guess an alternative would be to format an input like <code>730</code> to <code>07:30</code> ....</p>
  <p>I tried many different search terms searching the PySimpleGUI.py, in google, and on this site to no avail. I know one can format the output of the CalenderButton, but I don't know how this would help me, as I need to be able to insert a time directly.</p>
