Does anyone routinely use Julian dates

Every country in the world uses the International System (or SI) for weights and measures for all official transactions except for three. One is the United States. The other two are Burma and Liberia. I know that many countries (like the UK, for example) still have old, non-metric systems that are often used, but the official system in the rest of the world is SI or metric.

Julian dates: Unix-Linux

I like to use ISO standard dates http://en.wikipedia.org/wiki/ISO_8601

such as 2014-12-13 for tomorrow's date.

It is a standard, and they sort properly.
