Simple automation based on time ? Newbee

Im a newbee a few hours in to Home Assistant. I cant seem to figure out how to create a simple rule to turn on a light at a certain time. I used the GUI to build the commands below, the manual trigger works, but will not auto trigger at a certain time. What am doing wrong??? thx

 action:
  - service: light.turn_on
  alias: New Automation
  condition: []
  id: '1515555545149'
  trigger:
  - at: '22:40:00'
platform: time

That the manual trigger works says the action is correct.

Now, the GUI creates horribly formatted automations, and it looks like you may have missed a few lines, but the following should work:

- id: '1515555545149'
  alias: New Automation
  trigger:
    - platform: time
      at: '22:40:00'
  action:
    - service: light.turn_on
      entity_id: light.yourlight

Here is an example of one of mine.

Laying in bed last night thinking about this issue and a light came on, so to speak,
(exatcly one hour after I gave up) !

Really, my TIMEZONE was wrong in my config file. LOL

Newbee!
