Web Development

Here's the answer to your first question:

SELECT
crdate
FROM sysobjects
WHERE name = 'proc_name' and OBJECTPROPERTY(id, N'IsProcedure') = 1

As far as comparing procs across servers, I would say the easiest way would be to run sp_helptext on the procs on each server, then use a text comparison utility (like WinDiff) to do the diff.

Hope this helps.
