You might think that, but I just discovered that the 5-year-old software that I am working on was converting times from UTC by getting the current offset from UTC. No consideration was made for the actual date being converted. The people who wrote this weren't stupid, they just didn't really think through the problem. That, and the company had no culture of code reviews or even documented designs. The times, they are a changing.
Seriously, though, getting the current time is easy. Converting an arbitrary datetime for an arbitrary location involves a bit of thought. This is especially true when you have to deal with Arizona. And, that is without having to consider the conversion of historical data that occurred during different DST rules.
