calling systime() function by awk

[shmokarami]

Hi everyone,
I want to use "srand" in a program with "awk" on my mac,
and to generate different numbers I want to use systime() as seed.
But this error occurs:
"awk: calling undefined function systime"

Could you please let me know How I can solve the problem?

I did not see any function about time in " man awk" description.

You are mixing and matching things that aren't related.

I would recommend that you take a moment to read up and get familiar with what AWK is and does.

If you look at the Numeric Functions supported by AWK, you'll see the srand() without any argument uses the current date and time as the seed automatically. Providing a integer means that the random number will go up to that integer..

You are right.
