Trophies on your profile will show the hour and date when you unlocked them ...
For example each DLCs have a trophy for gaining a star and another for gaining ALL stars. If the save pops both trophies at the same time it will look like it was cheated.
The same applies to the unlock additional events trophies, if all pops at the same.
