28 /* Real time vs offline time
29  *
30  * When we run on live traffic, time handling is simple. Packets have a
31  * timestamp set by the capture method. Management threads can simply
32  * use 'gettimeofday' to know the current time. There should never be
33  * any serious gap between the two.
34  *
35  * In offline mode, things are dramatically different. Here we try to keep
36  * the time from the pcap, which means that if the packets are in 2011 the
37  * log output should also reflect this. Multiple issues:
38  * 1. merged pcaps might have huge time jumps or time going backward
39  * 2. slowly recorded pcaps may be processed much faster than their 'realtime'
40  * 3. management threads need a concept of what the 'current' time is for
41  * enforcing timeouts
42  * 4. due to (1) individual threads may have very different views on what
43  * the current time is. E.g. T1 processed packet 1 with TS X, while T2
44  * at the very same time processes packet 2 with TS X+100000s.
45  *
46  * In offline mode we keep the timestamp per thread. If a management thread
47  * needs current time, it will get the minimum of the threads' values. This
48  * is to avoid the problem that T2s time value might already trigger a flow
49  * timeout as the flow lastts + 100000s is almost certainly meaning the flow
50  * would be considered timed out.
