Finding the difference between two dates

[Divya Joseph]

Hi Team,

I am new to StreamSets, I am trying to find the difference between two dates using Expression Evaluator. PFA error details. Could you please help me how can I find the difference of two dates using Expression Evaluator. I have used datediff in the expression but I am not sure if datediff function is valid in StreamSets, If not what is the alternate options I can use to find the difference between dates. Thank you 

Regards,

Divya
