    NAME

    ftime - get date and time
     
    

    SYNOPSIS

    #include <sys/timeb.h>
    
    int ftime(struct timeb *tp);
    

     

    DESCRIPTION

    The ftime() function sets the time and millitm members of the timeb structure pointed to by tp. The structure is defined in <sys/timeb.h> and contains the following members:

    time_t           time;
    unsigned short   millitm;
    short            timezone;
    short            dstflag;
    

    The time and millitm members contain the seconds and milliseconds portions, respectively, of the current time in seconds since 00:00:00 UTC (Coordinated Universal Time), January 1, 1970.

    The timezone member contains the local time zone. The dstflag member contains a flag that, if non-zero, indicates that Daylight Saving time applies locally during the appropriate part of the year.

    The contents of the timezone and dstflag members of tp after a call to ftime() are unspecified.  

    RETURN VALUES

    Upon successful completion, the ftime() function returns 0. Otherwise -1 is returned.  

    ERRORS

    No errors are defined.  

    USAGE

    For portability to implementations conforming to earlier versions of this document, time(2) is preferred over this function.

    The millisecond value usually has a granularity greater than one due to the resolution of the system clock. Depending on any granularity (particularly a granularity of one) renders code non-portable.
