Take a look on the following example:

sql>CREATE TABLE test (updated TIMESTAMP(0)  DEFAULT current_timestamp());

operation successful (1.433ms)

sql>\d test

CREATE TABLE "sb_traf"."test" (

"updated" TIMESTAMP(0)  DEFAULT current_timestamp()

);

sql>CREATE TABLE test2 (LIKE test);

operation successful (1.102ms)

sql>\d test2

CREATE TABLE "sb_traf"."test2" (

"updated" TIMESTAMP(0)

);
