El segundo de efemérides es una unidad del sistema del tiempo que, cuando se utiliza como variable independiente en las leyes del movimiento que rigen el movimiento de los planetas y las lunas del sistema solar, permite a las leyes del movimiento predecir con exactitud las posiciones observadas de los cuerpos del sistema solar. Dentro de los límites de la precisión observable, los segundos de las efemérides tienen una longitud constante, al igual que los segundos atómicos. Esta publicación permitió elegir un valor para la longitud del segundo atómico que concordara con las leyes celestes del movimiento.<sup id="cite_ref-FOOTNOTEMarkowitz_Hall_Essen_Parry1958_5-0" class="reference separada"><a href="#cite_note-FOOTNOTEMarkowitz_Hall_Essen_Parry1958-5"><span class="corchete-llamada">[</span>5<span class="corchete-llamada">]</span></a></sup>&#8203; </p><p>En 1961, el <a href="/w/index.php?title=Bureau_International_de_l%27Heure&amp;action=edit&amp;redlink=1" class="new" title="Bureau International de l&#39;Heure (aún no redactado)">Bureau International de l'Heure</a> comenzó a coordinar el proceso UTC internacionalmente (pero el nombre Tiempo Universal Coordinado no fue adoptado formalmente por la Unión Astronómica Internacional hasta 1967).<sup id="cite_ref-FOOTNOTENelsonMcCarthy200515_6-0" class="reference separada"><a href="#cite_note-FOOTNOTENelsonMcCarthy200515-6"><span class="corchete-llamada">[</span>6<span class="corchete-llamada">]</span></a></sup>&#8203;<sup id="cite_ref-FOOTNOTENelsonMcCarthyMalysLevine2001515_7-0" class="reference separada"><a href="#cite_note-FOOTNOTENelsonMcCarthyMalysLevine2001515-7"><span class="corchete-llamada">[</span>7<span class="corchete-llamada">]</span></a></sup>&#8203; A partir de entonces, se produjeron saltos temporales cada pocos meses y cambios de frecuencia al final de cada año.

Pronto se decidió que tener dos tipos de segundo con longitudes diferentes, a saber, el segundo UTC y el segundo SI utilizado en el TAI, era una mala idea. Se pensó que era mejor que las señales horarias mantuvieran una frecuencia constante, y que esta frecuencia coincidiera con el segundo SI. Así, sería necesario basarse únicamente en los pasos de tiempo para mantener la aproximación del UT. Esto se probó experimentalmente en un servicio conocido como "Stepped Atomic Time" (SAT), que marcaba la misma frecuencia que el TAI y utilizaba saltos de 0,2 segundos para mantenerse sincronizado con el UT2.<sup id="cite_ref-FOOTNOTEMcCarthySeidelmann2009227_10-0" class="reference separada"><a href="#cite_note-FOOTNOTEMcCarthySeidelmann2009227-10"><span class="corchete-llamada">[</span>10<span class="corchete-llamada">]</span></a></sup>&#8203; </p><p>También hubo descontento con los frecuentes saltos en UTC (y SAT).

A finales de 1971, se produjo un último salto irregular de exactamente 0,107758 segundos TAI, con lo que el total de todos los pequeños pasos temporales y desplazamientos de frecuencia en UTC o TAI durante 1958-1971 fue exactamente de diez segundos, de modo que <span style="white-space:nowrap">1 de enero de 1972 00:00:00 UTC</span> fue <span style="white-space:nowrap">1 de enero de 1972 00:00:10 TAI</span> exactamente,<sup id="cite_ref-FOOTNOTEBlair_197432_12-0" class="reference separada"><a href="#cite_note-FOOTNOTEBlair_197432-12"><span class="corchete-llamada">[</span>12<span class="corchete-llamada">]</span></a></sup>&#8203; y un número entero de segundos a partir de entonces. Al mismo tiempo, se modificó la cadencia de UTC para que coincidiera exactamente con el TAI. El UTC también empezó a seguir el UT1 en lugar del UT2. Algunas señales horarias empezaron a emitir la corrección DUT1 (UT1 - UTC) para aplicaciones que requerían una aproximación más cercana a UT1 que la que ahora ofrecía UTC.<sup id="cite_ref-FOOTNOTESeidelmann_199285-87_13-0" class="reference separada"><a href="#cite_note-FOOTNOTESeidelmann_199285-87-13"><span class="corchete-llamada">[</span>13<span class="corchete-llamada">]</span></a></sup>&#8203;<sup id="cite_ref-FOOTNOTENelsonLombardiOkayama200546_14-0" class="reference separada"><a href="#cite_note-FOOTNOTENelsonLombardiOkayama200546-14"><span class="corchete-llamada">[</span>14<span class="corchete-llamada">]</span></a></sup>&#8203; </p> <div class="mw-heading mw-heading3"><h3 id="Número_actual_de_segundos_intercalados"><span id="N.C3.BAmero_actual_de_segundos_intercalados"></span>Número actual de segundos intercalados</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Tiempo_universal_coordinado&amp;action=edit&amp;section=3" title="Editar sección: Número actual de segundos intercalados"><span>editar</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>El primer segundo intercalado se produjo el 30 de junio de 1972.
