UNIVERSAL TIME [1 record]

English

Subject field(s)
  • Metrology and Units of Measure
  • Chronology
  • Mathematical Geography
DEF

Greenwich time calculated from midnight at the Greenwich meridian (rather than from noon).

OBS

In 1925 the numbering system for GMT was changed so that the day began at midnight, as did the civil day. Some confusion in terminology resulted, though, and in 1928 the International Astronomical Union changed the designation of the standard time of the zero meridian to Universal Time which remains in general use. The term GMT is still used for some purposes (navigation) in English-speaking countries.

DEF

Temps solaire moyen de Greenwich augmenté de douze heures, c'est-à-dire, dont le changement de quantième est à minuit plutôt qu'à midi.

OBS

Dans l'échelle de temps universel les jours sont comptés de 0 à 24 h avec changement de quantième à minuit. L'emploi [du terme temps moyen de Greenwich et] du sigle GMT ou de son équivalent français TMG est donc à proscrire.

OBS

temps universel (T.U.) : terme et abréviation en usage à Ressources naturelles Canada - Secteur des sciences de la Terre.
