Only Stable32 handles data gaps seamlessly. Give it a try (read the manual for 
details).

But also ask yourself how much gaps matter. Yes, they affect the accuracy of 
your y-axis sigma scale and your x-axis tau scale. A few seconds every 30 
minutes is, what, a 0.1% error? That's like one pixel in a ADEV plot; not 
significant.

What I've done when I need a perfectly seamless data set is just interpolate 
for rare and obviously missing phase data points. That keeps the timescale 
intact. This is especially important if you plan to Fourier transform the data: 
under no circumstances do you want to slip a sample in that case.
