Configurable delay using templating

Thanks everyone. Ultimately this is what I came up with:

In my included sensor.yaml:

    - platform: template
      sensors: 
        bathroom_delay:
          value_template: > 
              {% if (states.sensor.local_time.state > "05:00") and (states.sensor.local_time.state < "10:00") %}
                15
              {% else %}
                5
              {% endif %}

Then in my included script.yaml:

bathroom_motion_helper:
  sequence:
    - delay: "00:{{ states.sensor.bathroom_delay.state }}:00"
    - service: light.turn_off
      data:
        entity_id: light.over_sink_light_53

bathroom_motion_timer:
  sequence:
    - service: script.turn_off
      data:
        entity_id: script.bathroom_motion_helper
    - service: light.turn_on
      entity_id: light.over_sink_light_53
    - service: script.turn_on
      data:
        entity_id: script.bathroom_motion_helper

Finally in my automations.yaml:

- id: jwe001
  alias: Bathroom Motion Detected
  trigger:
  - entity_id: binary_sensor.eye_motion_71
    platform: state
    from: 'off'
    to: 'on'
  action:
  - alias: Turn on bathroom lights
    service: script.bathroom_motion_timer
  hide_entity: true

All the sensor created needs to be hidden from the interface and would not be necessary if we had a delay_template option.
