using timestamp in triggers

Now that I got my dumb syntax error out of my triggers they are working fine except for variables of type timestamp.

I have a table t1 (ts timestamp(6)) and t2 (ts timestamp) and what I want to do in a trigger is essencially

on update or insert into t1

...

   INSERT into t2 VALUES (:new.ts);
...

Except the value seems to fluxuate in the low (milli-second) digits. I assume that this is similar to the restriction that you can't access LONG datatype in triggers with :new or :old.

What I'm not sure of is what's the workaround?
