Y2K Matrix
This is a suite of utilities for
testing a Linux/UNIX server for date and time issues after the year
1999. It was developed for a client's HP-UX 10.20 and 11.0 32 and 64
bit servers. It contains a suite of utilities to test a UNIX
machine's date functions, including whether it is a 32-bit or 64-bit
operating system; date change utility for added functionality and
sanity-checking; and the actual y2kmatrix application itself that
creates a matrix of dates over the full range of the UNIX Epoch.
This software has been written and
compiled under the GNU
Public License and is freely available to anyone who wishes to
use it in helping provide assurance for their UNIX/Linux Year 2000
concerns. It has been ported on both RedHat 5.2 and Slackware 3.6
distributions on both 2.0.36 and 2.2.10 kernels. The y2kmatrix
utility has also successfully been compiled as both 32 and 64 bit HP
on 11.0 and 32 bit HP on 10.20 with a little hand holding. Please see
the INSTALL.hp-ux file for some notes I
made while trying to port to HP-UX. Anyone wants to clean up the
makefiles on this one, don't hesitate to send updates to me at Me
to include HP-UX porting facility.
Features:
y2kmatrix:
Outputs a text file with all of
the dates in the 32-bit UNIX Epoch in the following format:
YYYY-MM-DD HH:MM:SS JUL
AM/PM.[Weekday, Month DD, YYYY]
This can be compared to another
file created by a database, such as MySQL to verify dates are being
calculated correctly or performaing spot checks using another
tested utility to verify dates are accurate, and, of course,
there's always that good old calendar.
sqldates.sh
word
dtloop
This really awesome program
counts to 49680 and outputs the result to a text file
along with some other relevant date formatting data;
This is primarily useful for
creating a textfile for later upload into a database such as MySQL,
or Informix;
Seriusly, that's all this thing
does: count to 49680;
bit64
datechg
Safely change the date on your
UNIX/Linux machine, or output a simple human-readable formatted
date;
Requires root authority to
actually change the date;
Not just a mere side note, but, a very relevant point, was the use of MySQL
as the starting point to create a reliable matrix from whence to compare
dates that resulted from the y2kmatrix. The tool used was this database,
partly to test the voracity of it's claim on Year 2000 readiness, and partly
to assure myself that the databases I'm so reliant on are compliant. >:)
Well, I did mention validation of my personal MySqL databases was important.
After all, it handles my checking and savings accounts.
During development of the y2kmatrix, the original matrix created from MySQL
served as the bench-mark from which to verify, and was later used to validate
an Informix 7.3 dbase running on HP-UX 11.0 64-bit on a production 2000+ user
server, along with a couple 4GL tools. I'm very comfortable with the MySQL
date integrity implemented. But, remember; you can't sue me if something
breaks. Just read the License. Hopefully, that's not why you're here.
