1 Top and the Year 2000 2 3 The software package top will not be affected by years numbering 4 between 2000 and 2037. No portion of the top code stores dates on 5 disk. All date processing in top is performed with functions from the 6 Unix C library and Unix kernel. The specific functions are: time(2) 7 and ctime(3S). These functions deal exclusively with conventional 8 Unix time values (number of seconds since Midnight January 1, 1970 9 GMT) and produce strings with a 4-digit year. At no point in the code 10 for top are the last two digits used to represent a year. 11 12 Top and the Year 2038 13 14 In the year 2038 top will fail to represent the time of day correctly 15 on 32-bit Unix operating systems. This is due to a limitation in the 16 way Unix represents time. Top will only work on systems whose kernel 17 call "time" and C library call "ctime" have been adjusted to represent 18 time with a value greater than 32 bits. The exact date and time of 19 this failure is 3:14:08 January 19, 2038 GMT. Note that this failure 20 will only affect the display of the current time in the output from 21 top. 22 23 24 THERE IS ABSOLUTELY NO WARRANTY PROVIDED WITH THIS SOFTWARE. 25 Please see the contents of the file "LICENSE" for further 26 information. 27
