object."Last Modified On" vs getdate()

Hello DXL experts,

I am new to DXL (and this forum), and after reading the thread about variables of the Date Type not all being comparable (some are a string value), I have a question regarding the system object attribute "Last Modified On". Is the date value returned from "Last Modified On" able to be compared to date value returned from the getdate() function ?
