I'm no DB2 expert, but if 10% of your values are null, I don't think an index on that column alone will ever help your query.

SELECT my_field_A, my_field_B FROM mytable FORCE INDEX (index_name_on_time_id) WHERE time_id >= UNIX_TIMESTAMP('1901-01-01 00:00:00') AND time_id < UNIX_TIMESTAMP('....
That the full table scan is better.
