There are already some JMeter variables based on the time:
http://jakarta.apache.org/jmeter/usermanual/functions.html#predefinedvars
perhaps you could use
p${TESTSTART.MS}
as the variable name.
Of course that will only give a unique value per test.
As to the Javascript - did you check for errors in the jmeter log file?
The easiest way to test Javascript code is probably to use the BSF
Sampler - which supports Javascript (and Jexl).
Having developed the code there, you can then convert it to a
Javascript function call.
But remember to escape any commas in the script:
http://jakarta.apache.org/jmeter/usermanual/functions.html#how
Or I've just discovered that you can define the script as a variable
(e.g. SCRIPT on the test plan, and reference it thus:
${__javascript(${SCRIPT}))
There is no need to escape the commas in the SCRIPT variable, because
the above statement is parsed before the the variable is replaced by
its contents.
