Salesforce.com: LastModifiedDate vs. SystemModstamp

Hi All

According to SF's page on System Fields, SystemModstamp gets updated 'Date and time when this record was last modified by a user or by an automated process (such as a trigger). '.

Question:  Does anyone have a definitive list of 'or by an automated process'?

Reason I ask is because I have an SSIS package connecting to SalesForce.com where each Data Source has ... 'WHERE SystemModstamp > <@User::dt_last_success>', and I'm observing that I'm getting way more rows that are reflected in a day's data entry activity. I haven't proved this yet by doing a compare of rows across days, but that might be coming.

Thanks in advance. Jim

Think of anything that happens by the system AFTER a user clicks save:

Triggers
Workflow field updates
Rollup summaries causing triggers to fire
and possibly many other things.
So potentially the mod time can be > the success time if it happens slowly enough in SF to be > than the timestamp in the remote system.

And any of the above could result in changes in column values.
