I wonder how they keep aircraft from landing on top of each other on the runway when the skip forward or back?
The U.S. Federal Aviation Administration uses UTC for all operations. There is a stylized protocol for communicating times via voice radio, e.g., 19:20 UTC is transmitted as "won nin-er too ze-ro". Controllers can also communicate local time upon request and this must be stated clearly, e.g., 18:30 local time might be transmitted "wun ait tree ze-ro local". If there's any ambiguity about what "local" means, pilots and controllers are expected to be aware of and to handle it. For more, see: Federal Aviation Administration. Aeronautical Information Manual (2012-02-09, updated through 2013-08-22). Section 4-2-12 "Time". http://www.faa.gov/air_traffic/publications/atpubs/aim/aim0402.html
