Hello, I am working on this trigger where I want to update a custom date field only when certain fields on the table are changed. I am assuming that Contact and Person Account has shared fields, so how would I create this trigger? (may be 1 for Account and another for Contact?)

Thank you, a simple example would be great! :)
