Just time zones
This fascinating digital map from the ‘Cartographers without Borders’ website delineates global time zones. Since 1972, the modern time standard (UCT) has been based on an atomic clock attuned to the earth’s rotation. The UTC is the successor to the Greenwich Mean Time (GMT) and differs from this by no more than one second. Based on a full day, one would expect there to be 24 time zones. However, as many as 40 exist, as well as daylight saving time zones. ‘Indian Standard Time’ for example is equal to the UTC plus five and a half hours. The geopolitical determination of several countries and territories’ time zones is remarkable. For example, throughout China, including Taiwan, Chinese Standard Time (UTC plus 8 hours) applies. Iceland also uses UTC, although it lies significantly further to the west than Greenwich.
