With team. >> hes talking about his job at the u.s. naval observatory time service department. >> we provide official time for department of defense and gps. and via gps it goes to much of the world. >> its not an exaggeration to say, you are the timekeeper. >> yes, we are the timekeeper. >> and keeping time, precise time, is important. for the financial system. for the internet, for the pentagon. the department has more than 100 atomic clocks, and there are three different types. one measures t...

>> dr. matsakas is talking about his job at the u.s. naval observatories time service department. >> we provide the official time for gps and via gps, it goes to much of the world. >> so its not an exaggeration to say, you are the time keeper. >> yes, we are the time keeper. >> and keeping time, precise time, is important. for the financial system, for the internet, for the pentagon. the department has more than 100 atomic clocks, and there are three different types. one measures the oscillation...

Trump. >> somebody has to come out and tell it like it is. politicians are all talk and no action. we have to be less police callie police politically correct. >> he said if nbc is so weak and so foolish to not understand the serious illegal immigration problem in the united states coupled with the unfair trade deals we are making with mexico then their contract violating closure of ms. universe will be decided in court. nbc has not commented on a possible lawsuit. sometimes it feels like ther...

Choicehotels.com the addition of a leap second is supposed to allow the earths gradually slowing rotation to catch up with atomic clocks. the tinkering could actually effect some systems. last time this happened in 2012 and some websites all crashed. and more than 400 flights were grounded in australia. and perhaps more nerve wracking this is the first leap second added since markets went completely electronic. markets ending trading early actually just in case. for those outside the u.s. trad...

And get longer and the clock will get out of sync and things like that. now what happened is weve moved to using atomic clocks the clocks that break down the atoms, and that way we can see all sorts of important things and make them be on time and very accurate. like gps, for example, and computer systems and things like that. if we go by the earth, were not so much on time. if we go by the atomic clocks we are. >> so now were in good shape now that were observing this. life can continue on as w...

Align the official world time calculated by atomic clocks to the actual rotation of the earth. well, the change takes effect at 8:00 p.m. eastern time. it wont affect anyones daily lives but the tiny delay may cause issues for computer server servers but iphones and dvr clocks all going to be good today with one extra second thomas. >> what about the coffee timers? >> thats the most important thing, exactly. >> thank you. apple joins the heated streaming service with an update. apple music now...

One second. >> that vibration is sort of the smallest unit of time that we can actually measure. >> reporter: their goal is to make the most precise clock in the world. currently the source for precision time is gps satellite which contain atomic clocks used to synchronize clocks on the ground. but the pentagon worries the satellites could be jammed. so they want an even more accurate alternative. your wrist watch loses a second every 30 days. clocks on gps satellites lose a second every 30,000 ...

Every month? ppg correspondent barbara starr tells us about it. ♪ >> reporter: chicago asks the age old question and pentagon is looking for the answer. this high-tech lab of lasers and mirrors measures the movement of atoms, 429 trillion atomic vibrations add up to just one second. >> that vibration is sort of the smallest unit of time we can actually measure. >> reporter: their goal is to make the most precise clock in the world. currently the source for precision time is gps satellites whic...

Hes invested in rockets, atomic clocks. he thinks its cool and he wants to be cool to it and talk about it. and if theres a financial return there, great. i dont think hes trying to throw money away. but i just think he wants to be involved in a lot of very colonel things and that was definitely an appeal here, i hope. >> you wrote a blockbuster about what you think he might do at "the post" he said if you ever have a question, just look at amazon. what do you mean by that? >> lots of different ...
