It would also be useful to link this to required notifications of time zone
changes to IATA to update country information and local scheduled flight arrival
and departure times in SSIM, and the fines IATA levies for late notices: $8M for
Egypt in 2016.
Plus $2M in known business losses as a result of clocks being wrong and
schedules and deadlines being missed.
For airlines, if any crew misses a flight because of clock issues, that or a
later flight is cancelled, as there are limited standbys.
If business passengers miss flights, planes fly empty or become overbooked, so
some airlines lose and others gain $ks of business per flight.
Electrical utilities need to know when people and businesses are preparing for
and doing work to schedule generation, balance load, and reduce prices: last
minute changes costs money to satisfy: can be extra $ks/MWh.
Gas utilities need to nominate space on pipelines by daily deadlines or their
supplies do not get to market to meet contracts, penalties are incurred, some
companies lose money, other have equally large windfalls: can be $10Ms/day; some
people get extremely stressed then lose their jobs, others get huge bonuses!
Transit, shipping, and all modes of traffic get messed up because people and
goods are not travelling, available, or moving when expected, with costs and
Posters with experiences in other industries can add their own horror stories
relating to time and missed schedules!
Take care. Thanks, Brian Inglis Calgary, Alberta, Canada
