TDT is a joint venture between Southern Cross and WIN.

As defined, TCB ( as observed from the Earth's surface ) is of divergent rate relative to all of ET, T < sub > eph </ sub > and TDT / TT ; and the same is true, to a lesser extent, of TCG.

TDT is a uniform atomic time scale, whose unit is the SI second.

* Barycentric Dynamical Time ( TDB ) is similar to TDT but includes relativistic corrections that move the origin to the barycenter.

Tasmanian Digital Television ( TDT, callsign TDT-11 ) is a digital television station in Tasmania, Australia.

Scottsdale is served by television stations ABC TV, SBS, Southern Cross Tasmania, WIN Television, TDT and radio stations 7SD 540 kHz and Sea FM 99. 7 MHz, and Launceston newspaper The Examiner and local newspaper The North-East Advertiser.

The most commonly used test is the transmission disequilibrium test, or TDT.

In 1976 the IAU resolved that the theoretical basis for its current ( 1952 ) standard of Ephemeris Time was non-relativistic, and that therefore, beginning in 1984, Ephemeris Time would be replaced by two relativistic timescales intended to constitute dynamical timescales: Terrestrial Dynamical Time ( TDT ) and Barycentric Dynamical Time ( TDB ).

For practical purposes the length of the ephemeris second can be taken as equal to the length of the second of Barycentric Dynamical Time ( TDB ) or Terrestrial Time ( TT ) or its predecessor TDT.

A definition of a terrestrial time standard was adopted by the International Astronomical Union ( IAU ) in 1976 at its XVI General Assembly, and later named Terrestrial Dynamical Time ( TDT ).

One of two options was suggested ; Southern Cross would drop one of its affiliations ( either Seven or Ten ) and TDT would pick it up ; or TDT would also become a dual Seven and Ten affiliate, and carry the programs that Southern Cross didn't broadcast.

Southern Cross didn't want to disrupt its existing programming, so the agreement TDT signed with the Ten Network still allows Southern Cross to have ' first pick ' of Ten programming.

From its initial broadcast in late December 2003, to late January 2004, TDT showed a direct feed of ATV-10 in Melbourne.

Southern Cross dropped Rove Live and Totally Wild in 2004, Big Brother in 2006, The Bold and the Beautiful in 2007, Hueys Cooking Adventures, Australian Idol and Thank God You're Here in 2008 ( though it was brought back in 2009 with its move to Seven ), and Neighbours and The Simpsons in 2009, TDT now broadcast these shows.

For the 2010 Commonwealth Games ( which Network Ten has terrestrial broadcasting rights ) on One HD, TDT will use its digital channel 5 for the coverage.

When TDT premiered in 1967 it was the first regular nightly current affairs program on Australian TV, and it extended ABC ’ s award-winning coverage of current affairs, which had begun in the early 1960s with its flagship weekly program Four Corners.

TDT was renowned for its hard-hitting interviews, a craft brought to a high degree of perfection by Carlton and Negus ; the program subjected Australian politicians to a novel degree of questioning and raised the hackles of politicians on both sides who were unused to being placed under such scrutiny.

TDT won many awards during its run including Logie Awards for “ Best New Program ” in 1967, “ Most Outstanding Coverage of Political Affairs ” in 1971 and “ Outstanding Contribution to TV Journalism ” in 1977.

) In addition, TDB was to have ( as observed / evaluated at the Earth's surface ), over the long term average, the same rate as TDT ( now TT ).

TDT and TDB were defined in a series of resolutions at the same 1976 meeting of the International Astronomical Union.

In this role, TT continues Terrestrial Dynamical Time ( TDT ), which in turn succeeded ephemeris time ( ET ).

In 1991, in Recommendation IV of the XXI General Assembly, the IAU redefined TDT, also renaming it " Terrestrial Time ".

For applications at the Earth's surface, ET's official replacement was Terrestrial Dynamical Time ( TDT ), since redefined as Terrestrial Time ( TT ).

* Terrestrial Dynamic Time ( TDT ) replaced Ephemeris Time and maintained continuity with it.

The offset provided a continuity from Ephemeris Time to TDT.

TDT has since been redefined as Terrestrial Time ( TT ).

ET's direct successor for measuring time on a geocentric basis was Terrestrial Dynamical Time ( TDT ).

TDT was also renamed to Terrestrial Time ( TT ), because of doubts raised about the appropriateness of the word " dynamical " in that connection.

Its successor time scales, such as TDT, as well as the atomic time scale IAT ( TAI ), were designed with a relationship that " provides continuity with ephemeris time ".

The APTT ( plus 80: 20 mix ), dilute Russell's viper venom time ( DRVVT ), the kaolin clotting time ( KCT ), dilute thromboplastin time ( TDT / DTT ) or prothrombin time ( using a lupus sensitive thromboplastin ) are the principal tests used for the detection of lupus anticoagulant.

TDT also ran annual April Fool ’ s Day stories, including the “ Dial-O-Fish ” ( an electronic device attached to a fishing rod that could be set to catch any desired species ), a story alleging that the Sydney Opera House was sinking into the harbour, and a bogus report about the supposed abolition of the 24-hour clock and the introduction of a metric ( or decimal ) time system.

It was eventually realized that TDB was not well defined because it was not accompanied by a general relativistic metric and because the exact relationship between TDB and TDT had not been specified.

In 1969 the Gorton administration was severely embarrassed by a renowned This Day Tonight story in which a conscientious objector, who had been on the run from police for several months, was interviewed live in the studio by journalist Richard Carleton, who then posed awkward questions to the Army minister about why TDT had been able to locate the man within hours and bring him to the studio when the federal police had been unable to capture him, and the event was made even more embarrassing for the government because the man was able to leave the studio before police arrived to arrest him.

Evidence for this locus was also found using a transmission disequilibrium test ( TDT ) in 12 Bavarian families.

Evidence for this locus was also found by the TDT in a large Bavarian family, as well as in a German family, in which significant linkage to this locus was found.

TDT was the first digital-only commercial channel in Australia.

In 1967, he was the presenter on the Adelaide edition of This Day Tonight or TDT, a current-affairs broadcast at 7. 30pm.

Hale's popularity as the host of the South Australian edition of TDT was such that the ABC printed bumper stickers saying " I like Clive ".

China Television Company, Ltd. ( CTV, ) ( Formerly called Taiwan Daytime TV ( TDT ) in 1969-1975 ) was established on September 3, 1968 by the then-ruling Nationalist Party of the Republic of China ( Taiwan ).

This Day Tonight ( commonly abbreviated as “ TDT ”) was an Australian Broadcasting Corporation ( ABC ) evening current affairs program of the years 1967-1978.
