As DFC says, it is 'normal' for the controller to adjust any cleared level, as, for example, any level issued inbound to Innsbruck will be 'adjusted' by the controller for temperature. It is the pilot's responsibility to adjust other altitudes such as MSAs, MDAs, even DAs and DHs where necessary and any other altitudes he/she may compute/consider, including, for example, procedure platform altitudes, acceleration altitudes, EOI procedure altitudes and others. It is still wise to confirm in your own mind that the level issued by ATC is, in fact, 'safe'.
