[id], [date_created], [date_updated] not usable for calculation

[BusinessInsights]

Hi Sergej,

I cannot use [id], [date_created], [date_updated] for calculations. I just get a blank field. Other Fieldvariables [461] etc. are fine.

for context, please see
viewtopic.php?f=2&t=1290&p=5265#p5265

Thank you very much and keep up the great work!
Alex
