> FFT requires input data to be sampled with a constant sampling interval. You can use something like Lomb-Scargle to get a periodogram without needing it to be evenly spaced. This also has the benefit of potentially making the Nyquist limit much softer (depending on how randomly-variating the sample interval is)[1].
