Privilege	Description
FAULT_TIME_TRAVEL	Allows performing time travel experiments

‍

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 123.

Linux

The Time Travel experiment issues a settimeofday syscall. See settimeofday(2)

This experiment requires the SYS_TIME capability, which is enabled by default at installation time. See capabilities(7)
