I cannot say that I throughly know this. Most part of the below
answers is just from reading the sources:

AprEndpoint.java:
return Poll.create(size, pool, 0, timeout * 1000);
See also [1]
The ttl value is apr_interval_time_t, which is measured in microseconds.
The value for "timeout" may come from
org.apache.tomcat.util.net.SocketProperties.soTimeout, which defaults
to 20000 (20 seconds).
Thus 20000 * 1000;
