It is not just about programmers, it is just that the Earth is not considered an accurate enough clock anymore. We can do better with atomic clocks.

For day-to-day operations, we don't need the exact position of the sun in the sky, in fact, with time zones, we can be off by hours and still do business. Using the sun would be inconvenient anyways, as each location would need its own time. So for that, a few seconds is completely negligible.

Not many people care about the precise position of the sun in the sky as seen from an arbitrary location, so there is no real need to skew our overall more useful atomic clocks for this.

Maybe, in a distant future, people will need to update their time zones to catch up with what would be a noticeable shift, big deal...

Computers (and those who programme them) are there to serve humans (with a biology regulated by the Earth), not the other way around!

Human society screwed with biology in a big way since the industrial revolution. A few seconds, even minutes don't matter when business hours can disrupt sleep patterns of a significant part of the population by hours.

Terrestrial time don't serve society very well, as it is not very precise, it doesn't serve biology well either, as it is based on some arbitrary meridian instead of your actual location. Biology-compatible times would be in relation to sunrise and sunset, as it is sometimes done.
