APAR Error Description / Circumvention
-----------------------------------------------
An issue has been seen that needs to be resolved related to
certificates having an expiration date beyond Jan 19th 2038.
When a certificate is imported into IBM i using Digital
Certificate Manager (DCM) with a date that goes beyond January
19th 2038, the following error message is received.
"The validity period does not contain today or does not fall
within its issuer's validity period."
CORRECTION FOR APAR MA45022 :
-----------------------------
The issue that needs to be resolved is a well-known problem
known as the "Year 2038 problem".
A variable type named "time_t" is used by many system level
functions to help calculate time. The type "time_t" is defined
in our environment as a 32-bit signed integer and represents the
number of seconds since 00:00:00 on January 1st 1970.
The technical reason which causes the year 2038 problem to occur
is because the 32-bit time_t value will overflow at 3:14:07 UTC
on January 19th 2038. Therefore, any calculations using a
32-bit time_t variable on a date that is greater than January
19th 2038 will cause incorrect results.
To resolve this issue, the use of time_t in structures and
programs will need to be converted to use time64_t which is a
64-bit integer and can be used in time calculations with a date
many years into the future.
