Fuseaux horaires en Asie du Sud
South Asia (India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan) runs on a small set of tightly-clustered timezones — most of the region is between UTC+5 and UTC+6, with India's IST (UTC+5:30) being the reference clock. Aucune des grandes économies n’observe l’heure d’été, les compensations restent donc fixes toute l’année. The overlap window with both Europe and the US East Coast is compressed but usable — why so many global support / BPO operations base delivery here.
