I updated my clock. Why are the changes in the clock not visible?
Changes in a clock are not visible immediately, to prevent lost of talks and items in a timeline. Clock changes will have affect in all new timelines.
When you make changes on a clock, and want them to have affect in the current timeline, you'll need to re-generate your timeline. Therefor, go to the program schedule Station > Schedules > Programs. Make a change in this schedule (e.g. duration of a program, or add a new program).
Now, go to the current timeline. Since the program schedule has been changed, the timeline needs to be generated again. This action will build up your timeline from the clock and your schedules program. Your timeline now includes the changed clock and is now ready to use.
