The maximum delay in seconds before the input block considers an event to be old. The default value is 1 second. See also Input blocks and event timing.

Logging throttling in seconds. Periodic log messages (for example, those reporting changes in the number of events being dropped by the input block) will not appear more frequently than defined by this constant. The default value is 1 second. See also Input blocks and event timing.

The minimum wait time in seconds. Some blocks can generate output automatically, based on the rate of change of the output. This sets a lower limit on the time between such outputs. See also Common block inputs and parameters.
