While making our final descent into the airport I observed a complete loss of pressurization. I alerted the Captain to the situation by stating; 'I believe we lost the auto pressurization;' to which the Captain replied something to the effect of; 'Do not bug me with non emergencies;' or; 'I don't want to hear that right now;' something like that.I continued to work through the problem by switching to the Standby Mode. Upon doing so I noted no difference in the status of the pressurization; at which point I switched to the Manual DC Mode. At that point I was able to observe the outflow valve indicator driving to close verifying proper function of the manual mode. On approach I switched the system back to Auto (not functioning at this point) and continued with my Second Officer duties for approach. On the ground the Captain mentioned he did not feel it necessary for me to mention the failure during that phase of flight. I stated I disagreed; and the conversation did not really go any further. I finished my duties in the cockpit and secured the aircraft while the Captain and First Officer completed the paperwork. That afternoon I awoke to an email stating that the log had not yet been turned in. I called Flight Operations and they said that they had received the log. I asked if there where write ups and discovered that the issue had not been written up.  I also learned that our oil temperature gauge that was acting up had also not been written up. I promptly called the Captain and advised him of my concerns and he stated he would take care of it.  I also informed the other Captain on call in the event that they where asked to take the airplane prior to a solution being found.
A B727 Second Officer alerted the Captain about the Pressurization AUTO Controller failure on final approach; but the Captain dismissed him and he later learned the failure was not entered in the Maintenance Log.
