Clock Types
Time-of-Day
Time-of-day clocks are conventional clocks which show the current time-of-
day. In Bugclock systems, this is derived either from an incoming LTC or
VITC timecode feed or from the Imagestores internal battery-backed clock.
Timer
Timers are time displays typically controlled from GPI trigger signals. Timer
clocks can have rate and duration (Timer Start Time) set in Clock Builder.
The rate is positive for count-up timers and negative for count-down timers.
Rates can go from 1% to 200% to allow for clocks which count at non-
realtime rates. GPI triggers can be used to stop, start and reset timers.
Time-of-day countdowns
Time-of-day countdowns are typically used to display time remaining until a
particular event. They could, for example, be used to show hours, minutes
and seconds until a particular event or the number of days to Christmas. In
the Timing Modes section select the date (Countdown to) and time.
