• The difference between UT1 and UTC is known as DUT1 ."
• Afterwards these adjustments were made only in whole seconds to approximate UT1.
• The difference between UT1 and UTC is known as DUT1.
• Reinstating a claim by Vote's socks that GMT is UT1.
• Using these values, UT1 may be computed as:
• The time scale is UT1, which is similar to Greenwich Mean Time.
• The more current refined version of UT, UT1, is still in reality mean time at Greenwich.
• Whenever a level of accuracy better than one second is not required, UTC can be used as an approximation of UT1.
• In an astronomical context, " GMT " is a deprecated name for Universal Time, or sometimes more specifically for UT1.
• In maritime usage, GMT retains its historical meaning of UT1, the mean " solar " time at Greenwich.
• However, DUT can be added to UTC to correct it to within 50 milliseconds of UT1, reducing the error to only.
• They all vary with respect to each other, but UT1 and UTC are never more than 9 / 10 of a second apart.
• Despite Dmytruk's efforts, changes spearheaded at UT1 by a new boss eliminated sign-language services, forcing Dmytruk onto extended leave.
• UTC is kept within 0.9 second of UT1 by the introduction of one-second steps to UTC, the " leap second ".
• The mode of transmission is UT1 and UTC in units of one-fiftieth of a second encoded onto the once-per-second pulses.
• "' 37022 Robertovittori "'( 2000 UT1 ) is a Italian astronaut who flew on multiple missions to the International Space Station.
• At the same time, the tick rate of UTC was changed to exactly match TAI . UTC also started to track UT1 rather than UT2.
• Graph showing the difference between UTC ( based on an atomic clock with leap seconds ) and UT1 ( based on the movement of the Earth ).
• Some time signals started to broadcast the DUT1 correction ( UT1  " UTC ) for applications requiring a closer approximation of UT1 than UTC now provided.
• Some time signals started to broadcast the DUT1 correction ( UT1  " UTC ) for applications requiring a closer approximation of UT1 than UTC now provided.
