# Time zone

A **time zone** is a region o the Yird that haes taen up the same staundart time, for ordinar cried 'local time'. Maist adjacent time zones is preceese ae oor apairt, an bi convention computes thair local time as an affset frae Greenwich Mean Time (see UTC an aw).

Staundart time zones can be defined bi geometrically subdividin the Yird's spheroid intae 24 lunes (wedge-shaped sections), bordered bi meridians ilk ane 15° o longitude apairt. The local time in neeghbourin zones wad differ bi ae oor. Houaniver, poleetical an geografical practicalities can result in irregular-shaped zones that follaes poleetical mairches or that chynges thair time saisonally (lik wi daylicht saufin time), as weel as bein subject tae antrin redefineetion as poleetical condeetions chynges.
