15 minutes = 900 seconds.
The decay time is a varying timer (calculated by the router) which has to do
with how many times the route has already flapped and what the starting
sliding scale is. 1st decay appears to be right away, subsequent decays are
based on sliding timer.
Check out RFC 2439.

Subject: BGP Route Dampening
Can anyone confirm if I am right here:
Rack1R4#show ip bgp dampening parameters dampening 15 1000 3000 30
(route-map TASK_4.4 10)
Half-life time : 15 mins Decay Time : 370 secs
Max suppress penalty: 4000 Max suppress time: 30 mins
Suppress penalty : 3000 Reuse penalty : 1000
I understand that the half-life is 15 minutes and that the penalty will
reduce by half every 15 minutes. But what is the decay timer seen in the
above output. It is exactly half of the half-life timer. My thoughts are
this is the time after which the penalty will start to decay.
So after 6.5 minutes the penalty will start to decay until it reaches
15 minutes when it will have reduced to half.
