I think the idea is that we'd achieve the same effect by changing working hours. There's nothing sacred about 9-5. If you're dealing with people in different timezones, you need to know the offset of your timezones, and take DST into account. If this were changed, you'd need to know the offset of your timezones, and take local working hours into account.

The benefit is not having to upgrade all the numerous specialised systems that may or may not be supported anymore every time a politician decides to change the clock. Having to throw out or hack around timekeeping problems with outdated-but-working embedded equipment carries costs.

(This discussion is of course completely tangential to the article)
