I can supply what Oracle 12.1 does:

SQL> SELECT to_timestamp('2016-06-13 15:43:36', ' YYYY/MM/DD HH24:MI:SS') AS ts FROM dual;

TS
--------------------------------
2016-06-13 15:43:36.000000000 AD

SQL> SELECT to_timestamp('2016-06-13 15:43:36', 'YYYY/MM/DD  HH24:MI:SS') AS ts FROM dual;

TS
--------------------------------
2016-06-13 15:43:36.000000000 AD

SQL> SELECT to_timestamp('2016-06-13    15:43:36', 'YYYY/MM/DD  HH24:MI:SS') AS ts FROM dual;

TS
--------------------------------
2016-06-13 15:43:36.000000000 AD

(to_timestamp_tz behaves the same way.)

So Oracle seems to make no difference between one or more spaces.
