## tvalspec

Structure - Defines format of system time values.

### SYNOPSIS

    struct tvalspec
    {
           unsigned int       tv_sec;
           clock_res_t       tv_nsec;
    };

    typedef struct tvalspec tvalspec_t;

### FIELDS

tv_sec
  Seconds.

tv_nsec
  Nanoseconds.

### DESCRIPTION

The tvalspec structure defines the format of the time structure supplied to or returned from the kernel. This definition conforms to the Posix 1003.4 timespec definition where the tv_nsec structure member is valid if (0 =< tv_nsec < 109) and the time period described is ((tv_sec * 109) + tv_nsec) nanoseconds.
