There is no universal solution for the Year 2038 problem. For example, in the C language, any change to the definition of the time_t data type would result in code-compatibility problems in any application in which date and time representations are dependent on the nature of the signed 32-bit time_t integer.
A similar problem will occur in 2038 (the year 2038 problem), as many Unix-like systems calculate the time in seconds since 1 January 1970, and store this number as a 32-bit signed integer, for which the maximum possible value is 2 31 − 1 (2,147,483,647) seconds. [50] 2,147,483,647 seconds equals 68 years, and 2038 is 68 years forward from 1970.
Programs that process years as 16-bit values may encounter problems dealing with either the year 32,768 or 65,536, depending on whether the value is treated as a signed or unsigned integer. For the year 32,768 problem, years after 32,767 may be interpreted as negative numbers, [5] [87] beginning with −32,768 which may be displayed as 32,768 BC.
The 2038 problem is primarily a UNIX problem, but it also occurs in any program that uses the same Epoch. the same Tick and the same number of bits as Unix. The program does not have to be an operating system; although many programs simply use the same format as the underlying OS, others calculate dates internally.

The GPS week number rollover is a phenomenon that happens every 1,024 weeks, which is about 19.6 years. The Global Positioning System (GPS) broadcasts a date, including a week number counter that is stored in only ten binary digits, whose range is therefore 0–1,023.

This is a list of some of the more commonly known problems that are NP-complete when expressed as decision problems. As there are thousands of such problems known, this list is in no way comprehensive. Many problems of this type can be found in Garey & Johnson (1979).
