It covers all the basics, plus has the added feature of easily being able it to your warehouse with no storage cost. DATEDIFF(expr1,expr2) Use: SELECT DATEDIFF(___Bookings. Hi Aram, I don't believe we have such function readily available in Snowflake, so you can consider writing your own UDF to do this. Is there any inbuilt function that provides the timestamp instead of computing the datediff every time? In both cases above the output timestamp is epoch timestamp corresponding to the CURRENT_DATE (which is the current time in the snowflake account time zone).

Alternative for DATE_PART.
