Here are a few of mine. I like quartz watches when I travel because I don't have to remember to wind them and not too expensive when I lose them :-( as I have done twice.
India is a half-hour ahead of Pakistan to the west and a
half-hour behind Bangladesh to the east.
Iran is a half-hour ahead of its western neighbor Iraq while Afghanistan, just east of Iran, is an hour ahead of Iran but is a half-hour behind neighboring countries such as Turkmenistan and Pakistan.
Australia's Northern Territory and South Australia are offset in the Australian Central Standard Time zone. These central portions are a half-hour behind the east (Australian Eastern Standard Time) coast but an hour and a half ahead of the state of Western Australia (Australian Western Standard Time).
Most of Newfoundland and Labrador are in the Newfoundland Standard Time (NST) zone, which is a half-hour ahead of Atlantic Standard Time (AST). The island of Newfoundland and southeastern Labrador are in NST while the remainder of Labrador along with neighboring provinces New Brunswick, Prince Edward Island, and Nova Scotia lie in AST.
Nepal, is fifteen minutes behind Bangladesh, which is on a standard time zone. Myanmar (Burma), is a half-hour ahead of Bangladesh but an hour ahead of India. The Australian territory of the Cocos Islands shares the time zone of Myanmar. The islands of Marquesas in French Polynesia are a half-hour ahead of the rest of French Polynesia.
China has only one time zone even though it's 5 zones wide.
Although the world was divided into 24 zones, one for each hour (more or less) it now has about 40 different time-keeping regions.
