I've called time-coded shows before and people often ask me how it's different from a traditional show. In the past I've used the analogy of flying a plane. In a traditional show, you're calling each cue, giving standbys, etc... Think of this as flying the plane manually using each control lever, pedals, etc... With a timecoded show you're taking a more passive role, think of this as autopilot. The computer is taking commands based on what's been programmed. With autopilot on a plane, you've still got to have intimate knowledge of all aspects of the flight in case something goes wrong, and the same is true with a timecoded show.
Will you be running the automation? Calling a show to automation will take a bit of adjustment. If you're a technically minded person that adjustment should come a little easier. Basically, instead of calling the cue and the operator or stagehand taking the cue, you're simply going to be telling everyone what is happening. A good example would be something like "Stage Lift A moving in 3...2...1...moving". You'll have a timecode display at your call station and you basically call backwards based off of the time when the cue will happen. That's a very general overview of my experiences, if you have any more specific questions feel free to post here or PM me.
