Get Date Difference between two datetime fields in confiform

[Dhiraj Kr_ Gupta]

• I have two confiform datetime fields Date1 and Date2 and another confiform date time interval field as Datediff.

I want to get the date difference between Date1 and Date2 in the field Datediff.

I am using IFTTT but not getting the result as error showing End Date Missing.

IFTTT used

entryId=[entry.Id]&Datediff=([entry.Date1]-[entry.Date2])

Lastly I want 

entryId=[entry.Id]&Datediff=([entry._now]-[entry.created])

How can I do this

Datediff is a date time interval field?

what you have now is that you calculate the milliseconds between Date1 and Date2 (assuming Date1 is AFTER the Date2)

Date time interval expects you to provide the startDate and the endDate as a value, in the format of 

[entry.Date1]-[entry.Date2]

 (not a calculated value)

But a timestampForStart-timestampForEnd
