Simple way to get last SQL Server Service Restart

There are a lot of different ways to check when your sql instance last restarted but a coworker reminded me of the simple TempDB method.  Basically, every time that the SQL Server service restarts, TempDB is recreated.  So to find out the last instance restart, just run this:

SELECT CREATE_DATE FROM sys.databases where name=’tempdb’

It works on SQL2005+.  Old School!
