Sunset offset time

Ive upgraded to 0.86, and ive been going through my automations which had time references, and im not sure how to change an automation which uses a time offset on sunset. the currrent Automation has

- alias: Auto Lamps
  id: 'autolampson'
  trigger:
  - platform: sun
    event: sunset
    offset: -00:45:00
  action:
    service: light.turn_on
    entity_id: group.lamps
    
- alias: lights off
  id: 'autolampsoff'
  trigger:
  - platform: time
    at: 23:15:00
  action:
    service: light.turn_off
    entity_id: group.lamps

Can someone point out how to amend based on the new 0.86 changes?

Shouldn’t need any corrections. Check the docs.

Ive just reloaded again, and it has accepted the automation - Solved
