ECO KIT SUMMARY:
A dupatch-based, Early Release Patch kit exists for HP Tru64 UNIX 5.1B-2/PK4
that contains solutions to the following problem(s):
An enhancement has been made to the times(3) function that improves
performance on subsequent systems calls for the same process by internally
caching information. An additional enhancement has been to proc(4) such
that the creation time field returned by a stat(2) call contains a
process's actual creation time instead of the current system time.
The Patch Kit Installation Instructions and the Patch Summary and Release

and a summary of each patch. Please read these documents prior to
installing patches on your system.
