to_date() not works as described for pattern DD & HH

The Funktion ist described as

to_date(text, text) date convert string to date to_date('05 Dec 2000', 'YYYYMMDD')

The 2 Pattern DD/HH are not well working
All Digs ar counted from Position6/8 are counted as Days or Hour
and produce a future Date or error from a Timestamp in Milliseconds

The description

DD day of month (01-31)
HH hour of day (01-12)

Fore Example:
- Full Time in include ms 2015-12-02 11:59:09.001
-- Fulltimestamp 20151202115909001

SELECT to_date('20151202115909001','YYYYMMDD') AS der_2_december_eleven_a_clock
-> "5795177-12-29“ => fare away in the future

SELECT to_date('20151202115909001','YYYYMMDDHH') AS der_2_december_eleven_a_clock

ERROR: hour "115909001" is invalid for the 12-hour clock
HINT: Use the 24-hour clock, or give an hour between 1 and 12.

********** Fehler **********

ERROR: hour "115909001" is invalid for the 12-hour clock
SQL Status:22007
Hinweis:Use the 24-hour clock, or give an hour between 1 and 12.

- Full Time in include ms 2015-12-01 11:59:09.001
-- Fulltimestamp 20151222115909001

SELECT to_date('20151222115909001','YYYYMMDD') AS 22_december_eleven_a_clock

ERROR: value for "DD" in source string is out of range
DETAIL: Value must be in the range -2147483648 to 2147483647.

********** Fehler **********

ERROR: value for "DD" in source string is out of range
SQL Status:22008
Detail:Value must be in the range -2147483648 to 2147483647.

The other Pattern works as Described
SELECT to_date('20151202115909001','YYYYMMDDHH24') AS der_2_december_eleven_a_clock
-> "2015-12-02"

My first workaround in the script was to take only the first 8 Digs
SELECT to_date(left(‚20151222115909001‘,8),'YYYYMMDD') AS 22_december_eleven_a_clock
"2015-12-22"
other description of the timestamp works also fine
SELECT to_date(left('20151202115909001',8),'YYYYMMDDHH24MISSMS') AS der_first_december_eleven_a_clock
SELECT to_date('20151202115909001','YYYYMMDDHH24MI') AS der_2_december_eleven_a_clock
