it gave me
Code:
0.355u 1.00s 0:1.01 110.2% 0+0k 0+0io 0pf+0w
on the terminal, after printing the contents of the file that I've given as ARGV[0] . .
And yes, that file does not contain the above line . .
uname -a gives,
Code:
Linux <username> 2.6.18-274.3.1.el5 #1 SMP <date & time> x86_64 GNU/Linux
I am using Redhat 5.0 . .
Also, time sleep 10 gives,
Code:
0.000u 0.000s 0:10.00 0.0% 0+0k 0+0io 0pf+0w
so I guess you're on right track, Corona688
So, What does the rest four fields signify?
Thanks,

TIME(2) Linux Programmer's Manual TIME(2)NAME
time - get time in seconds
SYNOPSIS
#include <time.h>
time_t time(time_t *t);
DESCRIPTION
time() returns the time as the number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC).
If t is non-NULL, the return value is also stored in the memory pointed to by t.
RETURN VALUE
On success, the value of time in seconds since the Epoch is returned. On error, ((time_t) -1) is returned, and errno is set appropriately.
ERRORS
EFAULT t points outside your accessible address space.
CONFORMING TO
SVr4, 4.3BSD, C89, C99, POSIX.1-2001. POSIX does not specify any error conditions.
NOTES
POSIX.1 defines seconds since the Epoch as a value to be interpreted as the number of seconds between a specified time and the Epoch,
according to a formula for conversion from UTC equivalent to conversion on the naive basis that leap seconds are ignored and all years
divisible by 4 are leap years. This value is not the same as the actual number of seconds between the time and the Epoch, because of leap
seconds and because clocks are not required to be synchronized to a standard reference. The intention is that the interpretation of sec-
onds since the Epoch values be consistent; see POSIX.1 Annex B 2.2.2 for further rationale.
