An abbreviation for Central Daylight Time. During Daylight Saving Time the CST (Central Standard Time) time zone is adjusted by -1 hour -- thus making CDT a total of -5 hours different from GMT (Greenwich Mean Time) and UTC (Universal Coordinated Time).

CDT is -1 hour of EDT, +1 hour MDT, and +2 hours PDT.

An abbreviation sometimes used in British schools for "Craft, Design and Technology".

It covers a wide range of topics such as

  • Metal work
  • Wood work
  • "Technology" - may involve building things out of metal or wood, but often computer-interfaced or more "cross-disciplinary"
  • "Graphics" - technical design and drawing
  • Sometimes the more traditional art lessons are also included under CDT (eg Painting and Drawing, Printing, Pottery etc)

The facilities needed to teach CDT can be quite expensive - decent public schools (which are private schools... never mind) may have multiple workshops with proper industrial lathes, milling machines, drill-presses etc. There has also been a trend over the last 15 years to introduce CAM systems (Computer Aided Machining) - for example, a software package which allows you to design something that a lathe can make, and then send it straight to a computer controlled lathe which automates the entire process.

Many schools will also offer CDT courses to GCSE or A-Levels.
