There's good reason it's in the standard. Many applications of computer science rely on being able to accurately measure time. Having every second increased by a non-trivial amount (~0.001%) on some days, and not on others, will produce subtly wrong results in all kinds of fields, from manufacturing to astronomy. This was a bad, bad choice by Google.
