Common mistakes with London and Mexico City

  • Forgetting that the gap changes even though Mexico City never touches its clocks: London does, so a meeting fixed in Mexico City time moves by an hour for people in London.
  • Writing “GMT” all year for London. In summer the zone is British Summer Time; calendar apps handle it, but a typed time in an email can be read the wrong way.
