Top and the Year 2000
|
||
|
|
|
||
|
|
The software package top will not be affected by years numbering
|
||
|
|
between 2000 and 2037. No portion of the top code stores dates on
|
||
|
|
disk. All date processing in top is performed with functions from the
|
||
|
|
Unix C library and Unix kernel. The specific functions are: time(2)
|
||
|
|
and ctime(3S). These functions deal exclusively with conventional
|
||
|
|
Unix time values (number of seconds since Midnight January 1, 1970
|
||
|
|
GMT) and produce strings with a 4-digit year. At no point in the code
|
||
|
|
for top are the last two digits used to represent a year.
|
||
|
|
|
||
|
|
Top and the Year 2038
|
||
|
|
|
||
|
|
In the year 2038 top will fail to represent the time of day correctly
|
||
|
|
on 32-bit Unix operating systems. This is due to a limitation in the
|
||
|
|
way Unix represents time. Top will only work on systems whose kernel
|
||
|
|
call "time" and C library call "ctime" have been adjusted to represent
|
||
|
|
time with a value greater than 32 bits. The exact date and time of
|
||
|
|
this failure is 3:14:08 January 19, 2038 GMT. Note that this failure
|
||
|
|
will only affect the display of the current time in the output from
|
||
|
|
top.
