You can use current_timestamp at time zone tz_offset('EST'):
SQL> set linesize 132
SQL> column ct format a45
SQL> column ctz format a45
SQL> ALTER SESSION SET TIME_ZONE = 'Europe/Berlin';
Session altered.
SQL> select current_timestamp ct, current_timestamp at time zone tz_offset('EST') ctz from dual;
CT                                            CTZ
11-JUL-08 10.20.53.002549 PM EUROPE/BERLIN    11-JUL-08 03.20.53.002549 PM -05:00
SQL> ALTER SESSION SET TIME_ZONE = 'Canada/Mountain';
Session altered.
SQL> select current_timestamp ct, current_timestamp at time zone tz_offset('EST') ctz from dual;
CT                                            CTZ
11-JUL-08 02.21.02.344091 PM CANADA/MOUNTAIN  11-JUL-08 03.21.02.344091 PM -05:00
