Since "mesh" is undefined, it's hard to be sure... but it appears (from
this example at least) that a mesh lives in the INTERIOR of the plotted
curve or surface.
Hence, for instance:
timevector = Table[0.1*i, {i, 0, 10}];
epsilon = .0000001;
Plot[Sin[t], {t, First[timevector] - epsilon,
Last[timevector] + epsilon}, Mesh -> {timevector},
MeshStyle -> Directive[PointSize[Large], Red]]
shows all 11 mesh points.
