I'm trying to measure how long a particular socket has been
around. My plan is to record "jiffies" at the creation process of
the socket. Then, when I want to measure, I record again "jiffies"
in another variable and calculate the result. But I'm having the
1. In which file is "jiffies" defined?
2. What's the unit of "jiffies"? seconds, ms, or so??
3. I want to compare the "jiffies" result to TCP_TIMEWAIT_LEN,
which is defined in "include/net/tcp.h" as "(60*HZ)". What unit
conversion must I take to compare "jiffies" result with it??
4. If there are better ways, what're they?
Thanks a lot in advance.
