How to calculate difference between two Date and Time fields in SAP HANA Modeling?

Hi,

I need to calculate the difference between Two Date and Time fields using SQL Script in SAP HANA  or Information Models ( Views) in SAP HANA Modeling using HANA Modeling Wizard.

Suppose i have Start Date - 01.01.2014 & Start Time - 10:10:10 and End Date - 01.01.2015 & End Time - 15:10:10.

Can anyone suggest me how to calculate the difference between the Date & Times in the above example by using either SQL Script or HANA Modeling wizard.

Thanks in advance.

Regards,

Ramana.
