Siebel Financial Services CRM - Version [IP2014] to [IP2014] [Release V8]
Information in this document applies to any platform.


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().

---------------- [IP2014]

The following Clib.srand() is invoked then Clib.rand() always generates same number.

  var today = new Date;
  var vtimestamp = today.getTime();

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.
Same passwords are generated to every users.
