  1. TIME ZONES GMT : Greenwich Mean Time O Longitude : Observatory at Greenwich, England GMT (BKK) +7 GMT (TYO) +9

  2. การหาค่า GMT ของแต่ละเมือง GMT (BKK) +/- ค่า BKK Time Difference ของเมือง ที่ต้องการหาค่า GMT การหาค่า GMT ของลอนดอน GMT (BKK) +/- ค่า BKK Time Difference ของเมือง ที่ต้องการหาค่า GMT +7 -6 = +1 เพราะฉะนั้น LON มีค่า GMT เท่ากับ +1

  3. CALCULATION OF FLIGHT TIME Total Travel Time Note 1 : If a flight departs and arrives in the same time zone, it is a simple subtraction HKT-BKK Dep. 1310 Arr. 1435 = 1 Hour and 25 minutes BKK-CNX Dep. 1515 Arr. 1625 = 1 Hour and 10 minutes Plus : Ground time at intermediate (BKK) = 40 minutes Total Travel Time = 3 Hour and 15 minutes

  4. Note 2 : If the departure time and arrival time are in the different time zone. BKK (GMT+7) DEP 1700 (Local time) HKG (GMT+8) DEP 2040 (Local time) HKG (GMT+8) DEP 2240 (Local time) LAX (GMT-7) DEP 2050 (Local time)

  5. BKK (GMT+7) DEP 1700 (Local time) HKG (GMT+8) DEP 2040 (Local time) Convert 1700 to local time in HKG = 1800 Therefore, from arrival time 2040 in HKG deduct the adjusted departure in BKK. Arr. HKG 2040 local time Dep. BKK 1800 adjusted departure time Flying Time = 2 Hours and 40 minutes

  6. HKG (GMT+8) DEP 2240 (Local time) LAX (GMT-7) ARR 2050 (Local time) Convert 2240 to local time in LAX = 0740 Therefore, from arrival time 2050 in LAX deduct the adjusted departure in HKG Arr. LAX 2050 local time Dep. HKG 0740 adjusted departure time Flying Time = 13 Hours and 10 minutes

  7. Plus : Ground time in HKG Dep. HKG 2240 Arr. HKG 2040 Ground time = 2 hours Therefore, The Total travel time from BKK to LAX via HKG is 17 Hours and 5 minutes
