I can do this.

again. The broker could even dynamically adjust the rate based on an
estimate of supply and demand.

What information would you use to determine the time dynamically? I was
thinking in using {{{clientDeniedCount}}} and {{{proxyIdleCount}}} from
the metrics but it resets every 24 hours which can be a bit misleading.

\\
The second one seems like the best option. A timestamp can be confusing to
read and would depend on the operating system clock which can be offset.
