Question : Stored Procedure edit date - SQL Server 2000

I'm wanting to monitor some SQL Server 2000 databases and capture any instance of stored procedures being updated (particularly edits to existing SPs).

I believe this will do it in SQL Server 2005;
SELECT name, crdate, modify_date
FROM sys.objects
WHERE type = 'P'

From what I can see there does not seem to be any equivalent to *modify_date* in SQLS2000's sysobjects.

Any advice on this or alternate methods?

Ideally I am wanting to run a daily automated job that will email any Stored Procedure revisions on an exception basis. (I'm OK with the alert email etc... just don't seem to be able to capture  the change instance by query)

Regards,
