Supplemental:

Watcom C for QNX versions 8.51e and earlier had a faulty gmtime() 
library routine which incorrectly reports the day of week one
day off from March 1 2000 through to the end of the epoch. This
utility checks for the presence of the faulty library code in
binaries. Entire disks can be scanned for binaries or libraries
which may be affected by this problem by using find in conjunction
with check_y2k_lib, e.g.

find / -type f \( -perm -u+x -o -perm -g+x -o -perm -o+x -o -name '*.lib' \) \
     -echo \"{}\" | xargs check_y2k_lib -a

Note also that scans of the disk (above) should be done as root to
avoid the possibility of failing to detect bad binaries due to lack of
file permissions.

The check_y2k_lib program is itself a 16-bit binary which, for the
purposes of comparison, also contains the code sequences it is
designed to detect. Users of 32-bit QNX should note that the 16-bit
shared library (Slib16) must be installed in order to run the
check_y2k_lib utility.
