clock_gettime (nr 228)

Linux Signature

int clock_gettime(clockid_t clk_id, struct timespec *tp);

Description

Retrieves the time of the specified clock.

Current Implementation

Stub: Writes zero for both tv_sec and tv_nsec in the user-provided timespec struct. The clk_id parameter is accepted but ignored. Returns 0 (success).

This satisfies Rust std’s runtime init which calls clock_gettime(CLOCK_MONOTONIC, ...) but doesn’t depend on the actual time value.

Errors

Future Work

• Return real time based on the PIT/HPET/TSC timer.
• Distinguish CLOCK_REALTIME, CLOCK_MONOTONIC, etc.
