BZZT. Not quite, it has nothing to do with time, and nothing to do with getting an answer.
It's the number of hops (between routers) an IP packet is allowed to go towards the destination before being dropped. TTL is set to something, typically 128, but whatever. Each router which sees this packet decrements the TTL counter by 1. If a router ever sees an IP packet with its TTL set to zero, it drops the packet (and sends a ICMP TTL exceeded response back to the source of that IP packet).
