[Observium] Script environment variable OBSERVIUM_DURATION always 0s

hi, another issue i am finding with script variables is OBSERVIUM_DURATION. i am including in script notifications but it always reports as 0s (current date). so in other words, the duration of the alert is always reported to be 0s.

this seems like a bug as well?? should i put in a ticket for this also?

thanks again for all your help!
