The hard part of the 2038 problem is not the ABI changes, but all the higher-level systems and data storage formats that use 32 bit unix time. Such as file systems. Fortunately many of them can be adjusted to treat time as unsigned so they won’t need to break compatibility with old data, but it’s really hard to make a signed -> unsigned change without overlooking corner cases.
