I wish to have a time string ($t) like the one got by
$t = time();
However, it only returns nearest to seconds. How about mini-seconds?

Thanks in advance.

There should not be anything like that.

If your purpose is something like timing a process, try to have a look at the function 'times':

"this function returns a four-element array giving the user and system CPU times, in seconds (possibly fractional), for this process and the children of this process".

($user, $system, $cuser, $csystem) = times;

Example:

--//--
$start = (times)[0];
... # code to time
$end = (times)[0];
printf "that took %.2f CPU seconds\n", $end - $start;
--//--

If this answers your question, please let me re-submit it as an answer.

Rgds, julio

I really wish to get the time in detailed but not timing a program (I know of times()). In fact I wish to generate filenames that never be the same so I think of using the time strings to be the filenames.

Thanks very much for your comment.

Why not just appending the fractional part of the CPU time elapsed since the start of the script, to the time string you get from time().

This will end up with a string which will not tell you the correct time of creation (at least in its fractional part), but will surely make up unique file names.

With the permission of the other people, I think this can solve your question:

You can make use of the gettimeofday function.
Here is its declaration:

#include <time.h>

int gettimeofday (struct timeval *tp, struct timezone *tzp);

where timeval is:

struct timeval
{

unsigned long tv_sec;  /* seconds since 1, 1 1970 */
long   tv_usec;  /* Microseconds. Between 0 and 999.999 */

};

struct timezone
{

int tz_minuteswest; /* Local time variation in minutes, in relation to GMT */

int tz_dsttime; /* Saving daylights correction */

}

Also existing:

settimeofday ( struct timeval *tp, struct timezone *tzp);

}

Returned value: 0 if OK, -1 if not
