32 ftime \- return date and time
34 .B "#include <sys/timeb.h>"
36 .BI "int ftime(struct timeb *" tp );
38 Return current date and time in
40 which is declared as follows:
46 unsigned short millitm;
53 Here \fItime\fP is the number of seconds since the epoch,
54 \fImillitm\fP is the number of milliseconds since \fItime\fP
55 seconds since the epoch, \fItimezone\fP is the local time zone
56 measured in minutes of time west of Greenwich, and \fIdstflag\fP
57 is a flag that, if non-zero, indicates that Daylight Saving time
58 applies locally during the appropriate part of the year.
60 These days the contents of the \fItimezone\fP and \fIdstflag\fP
63 This function always returns 0.
65 This function is obsolete. Don't use it. If the time in seconds
72 gives nanoseconds but is not yet widely available.
74 Under libc4 and libc5 the \fImillitm\fP field is meaningful.
75 But early glibc2 is buggy and returns 0 there;
76 glibc 2.1.1 is correct again.
80 function appeared in 4.2BSD.
