* Time stamp types.
* Not all systems and interfaces will necessarily support all of these.
*
* A system that supports PCAP_TSTAMP_HOST is offering time stamps
* provided by the host machine, rather than by the capture device,
* but not committing to any characteristics of the time stamp;
* it will not offer any of the PCAP_TSTAMP_HOST_ subtypes.
*
* PCAP_TSTAMP_HOST_LOWPREC is a time stamp, provided by the host machine,
* that's low-precision but relatively cheap to fetch; it's normally done
* using the system clock, so it's normally synchronized with times you'd
* fetch from system calls.
*
* PCAP_TSTAMP_HOST_HIPREC is a time stamp, provided by the host machine,
* that's high-precision; it might be more expensive to fetch. It might
* or might not be synchronized with the system clock, and might have
* problems with time stamps for packets received on different CPUs,
* depending on the platform.
*
* PCAP_TSTAMP_ADAPTER is a high-precision time stamp supplied by the
* capture device; it's synchronized with the system clock.
*
* PCAP_TSTAMP_ADAPTER_UNSYNCED is a high-precision time stamp supplied by
* the capture device; it's not synchronized with the system clock.
*
* Note that time stamps synchronized with the system clock can go
* backwards, as the system clock can go backwards. If a clock is
* not in sync with the system clock, that could be because the
* system clock isn't keeping accurate time, because the other
* clock isn't keeping accurate time, or both.
*
* Note that host-provided time stamps generally correspond to the
* time when the time-stamping code sees the packet; this could
* be some unknown amount of time after the first or last bit of
* the packet is received by the network adapter, due to batching
* of interrupts for packet arrival, queueing delays, etc..
