For full details: http://blogs.dovetailsoftware.com/blogs/gsherman/archive/2011/10/07/case-aging-including-%E2%80%9Cpauses%E2%80%9D

Also requires the UpdateCaseClock.ps1 and UpdateCaseClock.bat scripts from my powershell repo on Github: https://github.com/gsherman/powershell

apply the case.clock.schemascript apply the GetCaseClockFunction apply the case.clock.view.schemascript

Note: for the GetCaseClockFunction, SQL Server must be at Compatibility level 90 (SQL Server 2005) or higher from sql server management studio, right click your database, choose Properties, then click on Options to see the compat level.
