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.
Identifier Description Time manipulation difftime: computes the difference in seconds between two time_t values : time: returns the current time of the system as a time_t value, number of seconds, (which is usually time since an epoch, typically the Unix epoch).
The maximum value of a signed 32-bit integer is 2 31 − 1, and the minimum value is −2 31, making it impossible to represent dates before 13 December 1901 (at 20:45:52 UTC) or after 19 January 2038 (at 03:14:07 UTC). The early cutoff can have an impact on databases that are storing historical information; in some databases where 32-bit Unix ...
datetime w/o time zone (long integer number of milliseconds since the Unix epoch) byte array (for arbitrary binary data) Boolean (true and false) null; BSON object; BSON array; JavaScript code; MD5 binary data; Regular expression (Perl compatible regular expressions ("PCRE") version 8.41 with UTF-8 support) [6]
Conversely, precision can be lost when converting representations from integer to floating-point, since a floating-point type may be unable to exactly represent all possible values of some integer type. For example, float might be an IEEE 754 single precision type, which cannot represent the integer 16777217 exactly, while a 32-bit integer type ...
The first 41 (+ 1 top zero bit) bits convert to decimal as 367597485448. Add the value to the X Epoch of 1288834974657 (in Unix time milliseconds), [5] the Unix time of the tweet is therefore 1656432460.105: June 28, 2022 16:07:40.105 UTC. The middle 10 bits 01 0111 1010 are the machine ID.
The actual sizes of short int, int, and long int are available as the constants short max int, max int, and long max int etc. ^b Commonly used for characters. ^c The ALGOL 68, C and C++ languages do not specify the exact width of the integer types short , int , long , and ( C99 , C++11 ) long long , so they are implementation-dependent.
It is therefore the maximum value for variables declared as integers (e.g., as int) in many programming languages. The data type time_t , used on operating systems such as Unix , is a signed integer counting the number of seconds since the start of the Unix epoch ( midnight UTC of 1 January 1970), and is often implemented as a 32-bit integer.
