This question is fairly straight forward, but I can't it figure out.

I am using the schema browser in the IDE to query some records and the SystemModstamp is actually 1 second later than the LastModifiedDate so they are obviously different. But hence the question: what is the difference?

LastModifiedDate is the date the record was last updated by a user. SystemModstamp is the date the record was last modified (by a user, workflow, trigger, etc.).


If you ask nicely, salesforce will let you set the last modified by (as in, you're importing records after a merger and want to maintain the created and modified stamps from the old system).

You can't ever touch the system modstamp.
