Meaning
The output shows the date and time when the snapshot was created and the packages that are part of the snapshot. Check to see that the date and time match the time when you created the snapshot.
You can compare the output of this command to the output of the show system software command to ensure that the snapshot contains the same packages as the software currently running the switch.
