The *ratelimit* directive supports a number of options (which can be defined
in any order):

*interval*:::
*interval* _interval_:::
This option sets the minimum interval between responses. It is defined as a
power of 2 in seconds. The default value is 3 (8 seconds). The minimum value
is -19 (524288 packets per second) and the maximum value is 12 (one packet per
4096 seconds). Note that with values below -4 the rate limiting is coarse
(responses are allowed in bursts, even if the interval between them is shorter
than the specified interval).
*burst*:::
*burst* _responses_:::
This option sets the maximum number of responses that can be sent in a burst,
temporarily exceeding the limit specified by the *interval* option. This is
useful for clients that make rapid measurements on start (e.g. *chronyd* with
the *iburst* option). The default value is 8. The minimum value is 1 and the
maximum value is 255.
*leak*:::
*leak* _rate_:::
This option sets the rate at which responses are randomly allowed even if the
limits specified by the *interval* and *burst* options are exceeded. This is
necessary to prevent an attacker who is sending requests with a spoofed
