clock_settime32¶

Intro¶

clock_settime32 - set the time of the specified clock

Description¶

clock_settime32() sets the time of the clock specified by which_clock to the time given by tp.

Advantages of using clock_settime32 is that it provides a way to set the time of the specified clock with a precision of nanoseconds, while drawbacks are that it doesn't change the system time, nor the time obtained with other clocks such as CLOCK_REALTIME.

Arguments¶

which_clock:clockid_t - ID of the clock to set.
tp:struct old_timespec32* - pointer to a struct containing the new time of the specified clock.

Available Tags¶

K - Originated from kernel-space.
U - Originated from user space (for example, pointer to user space memory used to get it)

Hooks¶

do_sys_clock_settime¶

Type¶

Kprobe + Kretprobe

Purpose¶

Hooked for observability purposes, to measure the execution time of clock_settime32 syscall and collect per-thread and per-process scenarios, such as library calls and user delay calls.

Example Use Case¶

clock_settime32 can be used to synchronize multiple applications running on the same machine by setting the same clock time with the same specified clock.

Issues¶

None.

clock_gettime32 syscall.
