Casting data types in custom fileds

[alexm1]

Hi all !

I’m quite new on Looker and slowly getting a grasp on how it works.

I’m trying to get a custom field which is an operation on a datetime (to which I’d add 18 hours, nothing crazy) in a string format. So basically I’m trying to cast this new datetime as a string.

Any thoughts? I haven’t seen a data casting function yet.

Thank you very much!
