Find closest value between time vectors of different lengths in MATLAB

I have 2 vectors, v1 and v2, containing date and time data. The vectors have different lengths, with length(v1)=15 and length(v2)=6. I want to obtain a new vector, v3, containing the closest values between v1 and v2, so I can accurately match the dates and times within v1 and v2. Does anyone have any idea how to achieve this? Thank you.

To find the closest value in v1 to each element of v2:

v1 = [1 3 5 3 4];
v2 = [4 5 6];                                               % // example data
[~, ind] = min(abs(bsxfun(@minus, v1(:), v2(:).')), [], 1); %'// compute all differences
                                                            % // and find index of minimizer
result = v1(ind);                                           % // build result

In this example,

result =
     4     5     5
