According to the posix spec, the times (2) structure is supposed be unchangable from boot to boot. It is affected by any clock changes and per the spec ( http://www.opengroup.org/onlinepubs/009695399/functions/times.html ) it shouldn't be. >How-To-Repeat: Have something using a times(2) structure to generate unique ID ( for the current run), cange the system time and you would be able to create duplicate time structurs. >Fix: Make times(2) work like the posix spec. It shouldn't be based on Epoch being 0, it should be based on "startup" time being the 0 time. >Release-Note: >Audit-Trail: >Unformatted:
