We employ a variety of techniques to examine the timing and variability of late time x-ray flares observed in GRBs by the XRT instrument aboard the
Swift spacecraft. These flares are thought to be indicative of late time activity by the central engine that powers the GRB and produced by means similar to those which produce the prompt emission. We use a Bayesian block denoising procedure to study the overall temporal properties of the flares and a Haar wavelet analysis to look for an evolution of the fundamental variability time-scale between the prompt and late time emission. We find evidence for pulse width evolution in the host frame of 17 flares as well as a qualitative trend of decreasing variability as a function of the flare's time of peak flux which we interpret as evidence of an expanding and cooling emitting region.
