Nevertheless, the line in the old observatory's courtyard today differs no more than a few metres from that imaginary line which is now the prime meridian of the world.

Historically, GMT has been used with two different conventions for numbering hours. The long-standing astronomical convention, dating from the work of Ptolemy , was to refer to noon as zero hours see Julian day.

This contrasted with the civil convention of referring to midnight as zero hours dating from the Roman Empire.

The latter convention was adopted on and after 1 January for astronomical purposes, resulting in a discontinuity of 12 hours, or half a day.

The instant that was designated "December Legally, the civil time used in the UK is called "Greenwich mean time" without capitalisation , according to the Interpretation Act , with an exception made for those periods when the Summer Time Act orders an hour's shift for daylight saving.

The Interpretation Act , section 9, provides that whenever an expression of time occurs in an Act, the time referred to shall unless otherwise specifically stated be held to be Greenwich mean time.

Under subsection 23 3 , the same rule applies to deeds and other instruments. Several countries define their local time by reference to Greenwich Mean Time.

Greenwich Mean Time is used as standard time all year round in the following countries and areas:. Since legal, political, social and economic criteria, in addition to physical or geographical criteria, are used in the drawing of time zones, actual time zones do not precisely adhere to meridian lines.

Retrieved 2 December Archived from the original on 25 January Universal Time UT , a term introduced in , initially represented mean time at Greenwich determined in the traditional way to accord with the originally defined universal day ; from 1 January as decided by the International Astronomical Union in Dublin in , at the initiative of William Markowitz this "raw" form of UT was re-labelled UT0 and effectively superseded by refined forms UT1 UT0 equalised for the effects of polar wandering [10] and UT2 UT1 further equalised for annual seasonal variations in Earth rotation rate.

Indeed, even the Greenwich meridian itself is not quite what it used to be—defined by "the centre of the transit instrument at the Observatory at Greenwich".

Although that instrument still survives in working order, it is no longer in use and now the meridian of origin of the world's longitude and time is not strictly defined in material form but from a statistical solution resulting from observations of all time-determination stations which the BIPM takes into account when co-ordinating the world's time signals.
