I understand where you are coming from on this. But what is you live in a state or country that does no observe DST? Won't those users also have a complaint?I don’t really think the solution to a simple few lines of software is me buying a $100 piece of hardware so it can adjust the time. I rarely adjust my lights so plugging in a USB cord makes sense for me.
Maintaining time accurately just seems like something a device which is time-based should perform without superfluous external hardware.
No one is forced to buy the reef link, If you don't buy it, the clock is still right half of the time. It's not like the animals care. To them either the light is on or off. The sun's schedule does not change with DST.
