No need to argue. 
Each solution has its pros and cons. You choose what works for you. 
Anyway, I have finally fixed my HA problem (it failed to update to the latest version due to a known problem).
Here is the Yaml code for the 2 triggers, 2 conditions solution, if you choose to use it:
alias: Latest of fixed time and sunset
description: ''
trigger:
- platform: sun
event: sunset
offset: '0'
- platform: time
at: '19:00'
condition:
- condition: state
entity_id: sun.sun
state: below_horizon
- condition: time
after: '19:00'
action:
- type: turn_on
device_id: (hidden for posting)
entity_id: light.bedroom_light
domain: light
mode: single
I think this is it. Not actually tested because too early in the day right now.
