41 capture device and when the networking stack time-stamps the packet;
43 the timer used to generate the time stamps might have low resolution,
48 a high-resolution timer might use a counter that runs at a rate
58 different CPU cores on a multi-core or multi-processor system might be
60 synchronized, so packets time-stamped by different cores might not have
68 the fraction-of-a-second part of the time stamp might roll over past
76 In addition, packets time-stamped by different cores might be
77 time-stamped in one order and added to the queue of packets for libpcap
82 packets; those time stamps are usually high-resolution time stamps, and
125 This is a low-precision time stamp, synchronized with the host operating

136 This is a high-precision time stamp, not synchronized with the host
142 done. This is a high-precision time stamp, synchronized with the host
147 done. This is a high-precision time stamp; it is not synchronized with
157 Host-provided time stamps generally correspond to the time when the
158 time-stamping code sees the packet; this could be some unknown amount of
165 and microseconds since that seconds value, even if higher-resolution
168 resolution than one microsecond, the additional digits of resolution are
177 call to specify the resolution of the time stamps to get for the device.
178 If the hardware or software cannot supply a higher-resolution time
183 call will have microsecond resolution.
189 routines can be used to specify the resolution of time stamps to be read
190 from the file; if the time stamps in the file have a lower resolution,
191 the fraction-of-a-second portion of the time stamps will be scaled to
192 the specified resolution.
196 routine returns the resolution of time stamps that will be supplied;
