Because the backtimer is an integral part of the clock display, if the backtimer is

shown, the clock display is also forced to a visible state. When hiding the

backtimer, though, the clock remains visible unless explicitly hidden.

How the Backtimer Works

To arrive at the over/under value, the remaining air play time of any item playing in Deck 1 (the on-air

channel) is summed with amount of content remaining in a given hour, starting with the "Next-to-Play"

item on the log.

Backtimer starting point for remaining log content

The remaining content total is compared with the time left in the hour (top of the next hour less current

clock time) to produce the over/under value displayed in the backtimer. If remaining content to play is

less than the amount of time remaining in the hour, a negative (-) value is displayed. If remaining

content to play is greater than the amount of time remaining in the hour, a positive (+) value is

displayed.

For best results, the log should contain a non-audio item (Directive, Program

Title, Log Note) at the top of each hour to clearly mark the start of an hour. If

the first non-audio element in a given hour is at a later time, audio elements

intended for the hour end up being a part of the preceding hour, which could

distort the backtimer value.

Backtimer resolution is one second, with each audio item rounded to the nearest second.
