Time Travel Experiment

No items found.

The Time Travel experiment modifies the system time of the target's operating system. This experiment also optionally blocks all traffic over the standard NTP port, which is equivalent to running a Blackhole Gremlin against outgoing port <span class="code-class-custom">123</span>.

Linux

The Time Travel experiment issues a <span class="code-class-custom">settimeofday</span> syscall. See settimeofday(2)

This experiment requires the <span class="code-class-custom">SYS_TIME</span> capability, which is enabled by default at installation time. See capabilities(7)
