(SYS_FUNC(time)): Use print_time_t for printing time. (SYS_FUNC(stime)): New function. * print_timespec.c (print_timespec_t, print_struct_timespec_data_size, print_struct_timespec_array_data_size, print_timespec): Add rtc argument, handle it. (print_timespec_t_utime): Call print_timespec_t with rtc=false when xlat_style is not abbreviated, call print_timespec_t with rtc=true instead of manual time stamp printing. (print_itimerspec): Call print_timespec_t with rtc=false. * print_timeval.c (print_timeval_t, print_struct_timeval_data_size, print_timeval, print_itimerval, print_timeval32_t, print_timeval32): Add rtc argument, handle it. (print_timeval_t_utime, print_timeval32_t_utime): Remove. (print_struct_timeval): New function. (print_timeval_utimes): Use print_struct_timeval instead of print_timeval_t_utime. * print_timex.c (print_timex): Add rtc argument, handle it. * printrusage.c (printrusage): Call print_struct_timeval with rtc=false. * sched.c (sched_rr_get_interval): Call print_timespec with rtc=false. * signal.c (rt_sigtimedwait): Call print_timespec with rtc=false. * time.c: Include "xlat/clocknames.h" under XLAT_MACROS_ONLY. (gettimeofday, settimeofday): Call print_timeval with rtc=true. (osf_gettimeofday, osf_settimeofday): Call print_timeval32 with rtc=true. (nanosleep): Call print_timespec with rtc=false. (getitimer, setitimer): Call print_itimerval with rtc=false. (osf_getitimer, osf_setitimer): Call print_itimerval32 wirh rtc=false. (do_adjtimex): Add rtc argument, handle it. (is_rtcid): New function. (clock_settime, clock_gettime): Call print_timespec with rtc=true if 0th argument is a real-time clock (as indicated by is_rtcid). (SYS_FUNC(clock_getres)): New syscall decoder. (SYS_FUNC(clock_nanosleep)): Call print_timespec with rtc=true if clock is realtime (as indicated by is_rtcid) and TIMER_ABSTIME is set in flags. (SYS_FUNC(clock_adjtime)): Call do_adjtimex with rtc=true if clock is realtime. * tests/adjtimex.c: Update expected output. * tests/clock_nanosleep.c: Likewise.
