Time command issuing all zeroes

I am trying to issue the time command on a program so I can see execution times but it is returning all zeroes. Like this:

time pdriver arg1 arg2
0.000u 0.000s 0:00.00 0.0% 0+0k 0+0io 0pf+0w

"0+0k 0+0io 0pf+0w" --> The "0+0io" may change sometimes to a different number.

How can I run the time command successfully? I'm using a unix terminal and my program is in c++.

#include <paradox.h> char * PX_timestamp2string(pxdoc_t *pxdoc, double timestamp, const char *format) DESCRIPTION
Creates a string representation of a paradox timestamp as specified in the parameter format.

A timestamp contains both time and date information. The format string contains chars which stand for certain values of the date/time. The following table lists all available characters with a meaning. All other characters are being copied unmodified to the output string. If a special character shall not be interpreted it must be preceded with a backslash. Characters and their meaning in date/time format string Character Meaning Y year, numeric, 4 digits y year, numeric, 2 digits m month, numeric n month, numeric, no leading zeroes d day of the month, numeric j T{ day of the month, numeric, no leading zeros T} H hour, numeric, 24 hour format h hour, numeric, 12 hour format G T{ hour, numeric, 24 hour format, no leading zeroes T} g T{ hour, numeric, 12 hour format, no leading zeroes T} i minutes, numeric s seconds, numeric A AM/PM a am/pm L boolean for leap year RETURN VALUE
