|
3018 # which meant that the time on one side of a mountain could differ greatly from |

3020 # instead, while airlines instead used UTC +03 (except in Dhahran, where they |

3022 # Company used Aramco time in eastern Saudi Arabia and airline time in western. |

3023 # (The American Military Aid Advisory Group used plain UTC.) Antar writes, |

3024 # "A man named Higgins, so the story goes, used to run a local power |
