Places choose a half or quarter hour when a whole hour would leave their clocks too far from their own sun-time. The places that use it are spread much wider than that one line. Of the main cities listed below, Mumbai (72.9° east) is the farthest west and Colombo (79.8° east) the farthest east. By the sun they are about 28 minutes apart, yet their clocks agree.
