Interpolation (see function interpol) or nearest neighbor. Example:

n=10
new_data=replicate(!values.f_nan,n)
new_time=lindgen(n)*300L

for i=0L, n-1 do begin
dist=min(abs(your_time - new_time[i]),pos)
if dist lt 5 then new_data[i]=your_data[pos]
endfor

In this example "your_time" and "your_data" are you arrays. Note that I set a tolerance of 5 seconds, you could change that...

Using interpol, would be something like:

new_data=interpol(your_data,your_time,new_time)
