kap-hide-clock 
Kap plugin - Hide the menu bar clock or Dato while recording
This hides the menu bar date/time widget while recording, which can be useful: 1. When you don't want to show that you recorded something at 4 AM. 2. If you edit a lot and leave out parts, the time will jump, which can be distracting.
Install
In the Kap menu, go to Preferences…, select the Plugins pane, find this plugin, and toggle it.
Usage
In the cropper or by right-clicking the tray icon, click the … icon, then Plugins and make sure Hide Clock is enabled.
