Unix Timestamp describes the point in time as the number of seconds that have elapsed since 00:00:00 (UTC), Thursday, 1 January 1970. The simple function implemented in this post helps you to calculate Unix Timestamp in Oracle Database. It can be useful in many different cases; i.e. integration with Java.
Below is an example of Unix Timestamp. More about it you cam find here.

Oracle Database hasn’t implemented UUID function yet, but you can use the following function:
function unix_timestamp(pi_date date) return number is c_base_date constant date := to_date('1970-01-01', 'YYYY-MM-DD'); c_seconds_in_day constant number := 24 * 60 * 60; v_unix_timestamp number; begin v_unix_timestamp := trunc((pi_date - c_base_date) * c_seconds_in_day); if (v_unix_timestamp < 0 ) then raise_application_error(-20000, 'unix_timestamp:: unix_timestamp cannot be nagative'); end if; return v_unix_timestamp; end unix_timestamp;
