  2. Leap year problem - Wikipedia

    en.wikipedia.org/wiki/Leap_year_problem

    The leap year problem (also known as the leap year bug or the leap day bug) is a problem for both digital (computer-related) and non-digital documentation and data storage situations which results from errors in the calculation of which years are leap years, or from manipulating dates without regard to the difference between leap years and common years.

    On 5 January 1975, the 12-bit field that had been used for dates in the TOPS-10 operating system for DEC PDP-10 computers overflowed, in a bug known as "DATE75". The field value was calculated by taking the number of years since 1964, multiplying by 12, adding the number of months since January, multiplying by 31, and adding the number of days since the start of the month; putting 2 12 − 1 ...

  4. Epoch (computing) - Wikipedia

    en.wikipedia.org/wiki/Epoch_(computing)

    Software timekeeping systems vary widely in the resolution of time measurement; some systems may use time units as large as a day, while others may use nanoseconds.For example, for an epoch date of midnight UTC (00:00) on 1 January 1900, and a time unit of a second, the time of the midnight (24:00) between 1 January 1900 and 2 January 1900 is represented by the number 86400, the number of ...

    Closely related to system time is process time, which is a count of the total CPU time consumed by an executing process.It may be split into user and system CPU time, representing the time spent executing user code and system kernel code, respectively.

    As mentioned, leap years typically take place every four years. That means the next leap years coming up after 2024 are 2028, 2032, 2036, 2040, 2044 and 2048. But again, it's not quite that easy.

    If a year is divisible by 100 but not divisible by 400, we skip the leap year. For example, 2000 was a leap year but 1700, 1800, and 1900 were not. The next skipped leap year will be in 2100.

    A year may be a leap year if it is evenly divisible by 4. Years divisible by 100 (century years such as 1900 or 2000) cannot be leap years unless they are also divisible by 400. (For this reason ...

  9. Year 2038 problem - Wikipedia

    en.wikipedia.org/wiki/Year_2038_problem

    FreeBSD uses 64-bit time_t for all 32-bit and 64-bit architectures except 32-bit i386, which uses signed 32-bit time_t instead. [23] The x32 ABI for Linux (which defines an environment for programs with 32-bit addresses but running the processor in 64-bit mode) uses a 64-bit time_t. Since it was a new environment, there was no need for special ...
