Time Span for Computers with No User Logon

Time Span for Computers with No User Logon

I just ran the prebuilt Computer with No User Logon report.    It is not clear to me how far back the report goes.    Several computers show up that I have logged onto within the last month, but not within the last week or so.     Can someone confirm how far back the report looks for no logons?
