Regularly, so-called “time-related issues” arise in IT. These involve technical limitations in the processing of date and time data. In addition to the well-known Year 2000 problem, the Year 2036 problem and the Year 2038 problem are currently the subject of particular discussion. This post provides a brief overview of both topics and explains why there is no risk to the IT systems at RWTH Aachen University.
What is the Year 2038 Problem?
The Year 2038 Problem affects older computer systems that internally store time as the number of seconds since January 1, 1970. This representation is also known as Unix time. In some older systems, the range of numbers used for this purpose is limited because time is stored as a 32-bit integer. On January 19, 2038, this range would be exhausted. In affected systems, this could lead to incorrect date information. In practice, this primarily affects outdated operating systems, older 32-bit systems, and specialized software that has not been updated or maintained for many years.
What is the Year 2036 Problem?
The Year 2036 Problem occurs in certain older time protocols, such as early implementations of the Network Time Protocol (NTP) version 3 and earlier. Here, too, the cause lies in a limited internal time representation that can overflow in February 2036. Modern implementations — particularly NTP version 4 and newer versions — account for this overflow and can continue to handle time data correctly.
Classification for RWTH Aachen
The central IT systems at RWTH Aachen, including learning platforms, administrative and web systems, and mobile applications, are not at risk from the Year 2036 problem or the Year 2038 problem. This is due to the use of modern 64-bit server architectures as well as current operating systems, databases, and time protocols. In addition, the IT Center conducts regular maintenance, updates, and security audits of all central systems, along with long-term technology and lifecycle planning. As a result, time and date information can continue to be processed correctly for many decades to come.
The Role of the IT Center
The IT Center at RWTH Aachen University continuously monitors technological developments and potential risks, such as time overflows. Issues such as the Year 2036 problem and the Year 2038 problem are integral parts of strategic system planning and are addressed at an early stage. If individual specialized or legacy systems are affected, they will be identified in a timely manner and either modernized or replaced.
The Year 2036 problem and the Year 2038 problem are well-known technical issues that primarily affect historical or very old systems. Therefore, there is currently no risk to RWTH Aachen’s IT systems, nor is any such risk foreseeable. RWTH Aachen University’s central systems are technically future-proof and are continuously being developed. The IT Center monitors potential timing issues and ensures the stable operation of the systems in the long term through forward-looking planning and regular modernization.
