Hi Randy,

In general it is a hard stop at 23:59.00. That is the case if, e.g.
 you get that number from typing in the time or selecting a time from the
dropdown. If, on the other hand, you selected the time by hand (clicking
and dragging in the window) then it could include up to 23:59.49.
(changing the time by typing in by hand will cause it to go straight to
23:59.00) There are several places where Flows will round to the nearest
second, so an occasional millisecond offset should not persist.

If you are looking at this level of detail, you should be aware that your
exporter might not be accurate to a millisecond level. Hardware
exporters often have a little bit of time skew relative to the server
running Flows, and sometimes truncate to the second anyway. Software
exporters are going to get the time that the packet came to the top of
the IP stack, not the time it arrived -- usually a vanishingly small
difference, but non-zero. When looking at a single exporter, everything
should be consistent, but the time skews may not be the same when
examining results from All Exporters on one graph.
