How to access process Instance start time in a script task?

[cchung]

Hi, I'm trying to access a process instance start time within a script task. 

Written in Javascript, I currently have

try{
//Get Process ID
    procID = execution.getProcessInstanceId();
    execution.setVariable("processId", procID);
//Get Process Definition Key
    procKey = execution.getProcessDefinitionKey();
    execution.setVariable("processDefinitionKey", procKey);
//Get Start Time
    procStart = execution.getStartTime()
    execution.setVariable("processInstanceStartTime", procStart);
}catch(e){
    execution.setVariable("errInit", e.message);
}

but the start time keeps coming in NULL, while everything else seems to work.  Any ideas on what I am doing wrong?

Hi,

I think that variable is missing.

You can use alternate way where create process variable and store date as soon as process start and use that variable.
