I do not want to create a temporary file.
I will give a more specific requirement.
I have to take a value from the XML file and change it into a unique text.
So what I am doing is appending the original text with process ID and Timestamp as I mentioned before.
If using timestamp is not appropriate please suggest me a more reliable solution.
------ From Prev Thread -----------------------------------
I have to create unique file names in a multiuser environment. So I am doing usertext_processID_TimeStamp to create unique file names. The following code is giving me the timestamp is seconds. 
 $unique_name = $user_name."_"."$$"."_"."$^T";

[download]
There are instances where two names are created in the same second and they are alike.
Is there a perlish way of getting time in nano seconds or milli seconds (or) I have to convert seconds to milliseconds manually?
Also let me know if there is a better way of creating unique names.

Thank you.
