-amin n
File was last accessed n minutes ago.
-anewer file
File was last accessed more recently than file was modified. If
file is a symbolic link and the -H option or the -L option is in
effect, the access time of the file it points to is always used.
-atime n
File was last accessed n*24 hours ago. When find figures out
how many 24-hour periods ago the file was last accessed, any
fractional part is ignored, so to match -atime +1, a file has to
have been accessed at least two days ago.
-cmin n
File's status was last changed n minutes ago.
-cnewer file
File's status was last changed more recently than file was modi‐
fied. If file is a symbolic link and the -H option or the -L
option is in effect, the status-change time of the file it
points to is always used.
-ctime n
File's status was last changed n*24 hours ago. See the comments
for -atime to understand how rounding affects the interpretation
of file status change times.
