help
Enable the unified clock_time subsystem which consolidates
hwtimer, ktime, and cputime into a single coherent framework.
This subsystem provides:
- Clocksource: Free-running counter for timekeeping
- Clockevent: Programmable timeout events
- High-resolution timers (hrtimer)
- POSIX clock support
- Boottime tracking
- CPU time APIs (clock_cpu_*, rt_cputime_*)
- Boottime APIs (rt_boottime_*)
