+--vm-time-correlation[=OPTIONS]::
+       Some architectures may capture AUX area data which contains timestamps
+       affected by virtualization. This option will update those timestamps
+       in place, to correlate with host timestamps. The in-place update means
+       that an output file is not specified, and instead the input file is
+       modified.  The options are architecture specific, except that they may
+       start with "dry-run" which will cause the file to be processed but
+       without updating it. Currently this option is supported only by
+       Intel PT, refer linkperf:perf-intel-pt[1]
