Symptoms
Statement of Issue:
-----------------------
Customer wants to generate different password by using Clib.rand() method.
- When Clib.srand() uses timestamp as seed number, Clib.rand() always generates same number. This is unexpected behavior.
- When Clib.srand() uses the seed number generated by Operating System(OS), Clib.rand() generates different number. This is expected behavior.
Customer's requirement is to explicitly use seed number in Clib.srand().
Environment:
----------------
8.1.1.14 [IP2014]
Steps:
--------
The following Clib.srand() is invoked then Clib.rand() always generates same number.
var today = new Date;
var vtimestamp = today.getTime();
Clib.srand(vtimestamp)
Error:
------
No error message.
Always same random number is generated.
Expected Behavior:
-----------------------
Clib.rand() mehoud should generated different number every time it is invoked.
Actual Behavior:
-------------------
Clib.srand() method generates same number when Clib.srand() uses timestamp as seed number.
If Clib.srand() uses the seed number generated by OS, Clib.rand() works fine.
Business Impact:
--------------------
Customer's initial password generation is not working.
