How to tell when a ext2,3,4 filesystem was last checked ( fsck) ?

The tune2fs command can list the contents of the superblock and provide information on the filesystem, one parameter is when the last time an 'fsck' was run on the filesytem.
tune2fs -l /dev/mapper/mpatha |grep "Last checked"
Last checked: Sun May 26 07:42:25 2013
-l List the contents of the filesystem superblock, including the
current values of the parameters that can be set via this pro-
gram.
