I tried using pfGetTime()(?) but it often returned strange results. Was this on an IO2 system? You'd know if "hinv|grep IO2" says something. Otherwise, you have an unexpected bug.

Date: Mon, 11 Oct 93 14:41:57 -0700 From: Jim Helman Status: OR where to get the time is a different story. I tried using pfGetTime()(?) but it often returned strange results. There was a bug in 1.0 (fixed in 1.1) which caused pfGetTime() to occasionally return bad values (off by 4000+ seconds!!!) on machines without a fast counter, e.g. PowerSeries/IO2. But if you've seen bad time values on an Indigo, Indigo2, PI/35, PowerSeries/IO3, Crimson, Onyx running any version of Performer or on an Indy running the 1.2 beta, speak up. rgds, -jim helman jimh@surreal.asd.sgi.com 415/390-1151
