# Sona ng oras

Pamantayang Sona ng Oras ng Daigidig noon pang 2011.
Ang time zone ay isang lugar na nagmamasid sa isang pare-parehong karaniwang oras para sa legal, komersyal at panlipunang mga layunin. Ang mga time zone ay may posibilidad na sundin ang mga hangganan sa pagitan ng mga bansa at kanilang mga subdibisiyon sa halip na mahigpit na sumunod sa longitude, dahil ito ay maginhawa para sa mga lugar sa madalas na komunikasyon na panatilihin ang parehong oras.

Ang bawat time zone ay tinutukoy ng isang karaniwang offset mula sa Coordinated Universal Time (UTC). Ang mga offset ay mula UTC−12:00 hanggang UTC+14:00, at kadalasan ay isang buong bilang ng mga oras, ngunit ang ilang mga zone ay na-offset ng karagdagang 30 o 45 minuto, tulad ng sa India at Nepal. Ang ilang mga lugar sa isang sona ng oras ay maaaring gumamit ng ibang offset para sa bahagi ng taon, karaniwan ay isang oras bago sa panahon ng tagsibol at tag-araw, isang kasanayang kilala bilang daylight saving time (DST).

## Talaan ng mga UTC offsets

Sona ng oras sa mundo
Sa talaan sa ibaba, ang mga lokasyon na gumagamit ng daylight saving time (DST) ay nakalista sa kanilang UTC offset kapag ang DST ay walang bisa. Kapag ang DST ay may bisa, humigit-kumulang sa panahon ng tagsibol at tag-araw, ang kanilang UTC offset ay tataas ng isang oras (maliban sa isla ng Lord Howe, kung saan ito ay tumaas ng 30 minuto). Halimbawa, sa panahon ng DST, sinusunod ng California ang UTC−07:00 at ang United Kingdom ay nag-oobserba ng UTC+01:00.
