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.
