• Proceed to Step 1 in the section titled "Loading Instructions" below.
Reasons for the GTS V2.2.0 Yr 2000 Enhancement:
• The purpose for this enhancement is to provide both GTS and the SCO Xenix operating
system support for the year 2000 and beyond.
• The year 2000 fix in GTS V2.2.0 Patch 5 did not include the SCO Xenix year 2000 fixes
and was therefore not a complete year 2000 update. You must load this enhancement to
have full GTS and SCO Xenix support.
Problems addressed in this enhancement:
• Disk 1 of 2 of the GTS V2.2.0 Yr 2000 Enhancement is actually an SCO Xenix support
supplement disk XNX427C. This support supplement contains updated Xenix binary
files.
• Disk 2 of 2 of the GTS V2.2.0 Yr 2000 Enhancement contains files needed to correct
problemsfound in theGTS softwarewith handling oftheyear2000 andgeneral problems
experienced while setting the date.
Both disk 1 and 2 address the following problems:
• The "year 2000" problem
Setting any date from January 1, 2000 on actually sets the year to 1970 instead.
• The "leap year" problem
Setting the time on the TMS controller to February 29, 2000 will actually set the date to
March 1, 2000 instead.
• System Errors while setting the date
When changing the date backward while logged into an off-line network, system errors
occur. When these errors appear, you are then denied access to all networks.

Caveats
1. Before you load the GTS V2.2.0 Yr 2000 Enhancement, please load all of the needed,
previously released GTS V2.2.0 patches.
2. Any subsequent release from this enhancement will have year 2000 support already built
in.
3. If you load this enhancement and then load a previously released patch, the contents of
that patch will NOT have year 2000 support and will cause the patched application to
have inconsistent date and time functionality.
4. If you DO load a patch released before the GTS V2.2.0 Yr 2000 Enhancement after you
have loaded this enhancement, you MUST perform the following:
a) Shutdown the controller and disable auto-login.
b) Reboot the controller.
c) When the Login: prompt appears, press ALT-F2
d) Log in as gts
e) Type cd exe
f) Type fix2000 -p *
(This will take about five minutes to complete.)

Loading Instructions
GDC 036R903-22011 5
g) Press ALT-F1
h) Log in as gts (runs the GTS software)
5. Due to the way UNIX represents the date internally, dates after the year 2037 are not
supported.
Note Since this is a Xenix "tar" disk, rather than a release disk, this enhancement is not
loaded via the "Load a Software Release" function in the "Controller Mainte-
nance" screen. Neither disk will be identified using the "Identify a Floppy Disk"
poke point in the "Controller Maintenance" screen.
