After a time of silence, I come back to this blog to explain one of the most fundamental concepts with completely different visions between astronomers and engineers: the time. One might think that measuring time is a simple thing, you only have to keep adding seconds and everything is solved. If that was the case, why last December 31st had an extra second? In this post, I explain some of the existing time scales and one of the more deeply disconcerting time concepts: the leap second.
If you came to this page by chance, you might be wondering what the hell is a support astronomer. In the very first post of this new blog, I give you all the details.
