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:.
