We have this weird issue where certain opportunities are being updated around the same time each day, but I cannot figure out for the life of me how this is happening. There are no batch processes/future calls that run during this time that update opportunities. There are processes that add a chatter post to certain opportunities during this time, but I don't think that should update opps.
I have also checked the login history for the lastmodified user to ensure that there are no api logins during this time.
I have also checked to ensure no time-based workflow occurs on the opportunity.
