Last nn {periods} is always relative to the currently configured "today date."
The today date is probably overridden in PMF settings at your site.
Look in Manage > Settings > System. What is Today Date set to?
If it's set to a point in the time dimension, the date has been overriden to a single point in time. That capability is mostly used when doing a demo using fixed historical data and probably isn't right for a live production version of PMF.
If it's set to System Clock Date, it will pick up the current date on the server clock as your current point in time.
It could also be set to Use Custom Procedure, in which case your current time is set with a FOCEXEC. If that's the case, you should check that procedure - it's generally a custom-written procedure used at your site only (in case you want to do things like set the current date to the current date - 1 month, or some such).
