Inject enhanced, how often will be evaluated a offset variable (global variable)

Hi there,

I'm using the inject enhanced node + dashboard time selector to make the point in time injection parameterizable.
The inject node is setup on a daily execution at 0:00. With a time selector I can manipulate the exact time safed to a global variable, when it should be fired. This variable is used as millisecond based offset in injection node. So far that works. But I'm not sure, how often will inject node evaluates eventual changes on this global variable? Does that only recognize it on node-red startup or flow redeployment?

Maybe I'm using that in a wrong way. But is there a better way to param a time specific injection via UI Dashboard instead of hard code the time in IDE?

Thanks in advance.

Something like this: Dynamic cron schedules / timers via dashboard control (flow) - Node-RED
