+ tai:
+ This is the tai clock (CLOCK_TAI) and is derived from the wall-
+ clock time. However, this clock does not experience
+ discontinuities and backwards jumps caused by NTP inserting leap
+ seconds. Since the clock access is designed for use in tracing,
+ side effects are possible. The clock access may yield wrong
+ readouts in case the internal TAI offset is updated e.g., caused
+ by setting the system time or using adjtimex() with an offset.
+ These effects are rare and post processing should be able to
+ handle them. See comments in the ktime_get_tai_fast_ns()
+ function for more information.

To set a clock, simply echo the clock name into this file::
# echo global > trace_clock
