In 1969, Elias Antar wrote that although a common -# practice had been to set one's watch to 12:00 (i.e., midnight) at sunset - -# which meant that the time on one side of a mountain could differ greatly from -# the time on the other side - many foreigners set their watches to 6pm -# instead, while airlines instead used UTC +03 (except in Dhahran, where they -# used UTC +04), Aramco used UTC +03 with DST, and the Trans-Arabian Pipe Line -# Company used Aramco time in eastern Saudi Arabia and airline time in western. -# (The American Military Aid Advisory Group used plain UTC.) Antar writes, -# "A man named Higgins, so the story goes, used to run a local power -# station. One day, the whole thing became too much for Higgins and he -# assembled his staff and laid down the law. 'I've had enough of this,' he -# shrieked. 'It is now 12 o'clock Higgins Time, and from now on this station is -# going to run on Higgins Time.' And so, until last year, it did." See: -# Antar E. Dinner at When?
