Hello,
The current_timestamp return the constant value in a transaction. So use
clock_timestamp().
Example:
create or replace function fx_nish()
returns text language plpgsql as
$$
declare
x timestamp with time zone;
y timestamp with time zone;
begin
x:= clock_timestamp();
perform pg_sleep(5);
y:= clock_timestamp();
if x=y then
return 'SAME';
else
return 'DIFFERENT';
end if;
end;
$$
;
postgres=# select fx_nish(); fx_nish
-----------DIFFERENT
(1 row)

Thanks and Regards,
