+Set the time the filesystem was last checked using
+.BR  e2fsck .
+This can be useful in scripts which use a Logical Volume Manager to make
+a consistent snapshot of a filesystem, and then check the filesystem 
+during off hours to make sure it hasn't been corrupted due to 
+hardware problems, etc.  If the filesystem was clean, then this option can 
+be used to set the last checked time on the original filesystem.  The format 
+of 
+.I time-last-checked
+is the international date format, with an optional time specifier, i.e.
+YYYYMMDD[[HHMM]SS].   The keyword 
+.B now
+is also accepted, in which case the last checked time will be set to the 
+current time.
