What does GMAT mean?

The Greenwich Mean Astronomical Time (GMAT) is an older form of noon-based astronomical convention for Greenwich Mean Time. In Greenwich Mean Astronomical Time the day beginning is considered at noon rather than midnight. It was used by astronomers before 1925 to avoid the need to change date during the night.
