From 8d6c8b941116e3295355ff9fc801a61738977787 Mon Sep 17 00:00:00 2001 From: Quincey Koziol Date: Tue, 25 Jan 2011 14:16:03 -0500 Subject: [svn-r19989] Description: Finish implementing time tracking for read & seek operations in the 'log' VFD. Also clean up code and track total time during all read/write/seek operations.
