"The DEFAULT constraint specifies a default value to use when doing an
INSERT. The value may be NULL, a string constant or a number. "; using
a function as a default is not covered.
A trigger can probably achieve what you want :
create table tst( id integer primary key, ts integer default
current_timestamp );
create trigger tst_update_ts after insert on tst begin
update tst set ts = case strftime( '%s', ts ) not null when 1
then strftime( '%s', ts ) else ts end where id=new.id;
end;
insert into tst( id ) values( null );
insert into tst( id ) values( null );
select * from tst;
1|1225703251
2|1225703259
insert into tst values( null, 'my birthday' );
select * from tst;
1|1225703251
2|1225703259
3|my birthday
