File system creation time

To determine the time and date a file system was created, you can use the getlvcb command. First, figure out what the logical volume is that is used for a partical file system, for example, if you want to know for the /opt file system: 

# lsfs /opt
Name         Nodename Mount Pt VFS   Size    Options Auto Accounting
/dev/hd10opt --       /opt     jfs2  4194304 --      yes  no
So file system /opt is located on logical volume hd10opt. Then run the getlvcb command: 
# getlvcb -AT hd10opt
  AIX LVCB
  intrapolicy = c
  copies = 2
  interpolicy = m
  lvid = 00f69a1100004c000000012f9dca819a.9
  lvname = hd10opt
  label = /opt
  machine id = 69A114C00
  number lps = 8
  relocatable = y
  strict = y
  stripe width = 0
  stripe size in exponent = 0
  type = jfs2
  upperbound = 32
  fs = vfs=jfs2:log=/dev/hd8:vol=/opt:free=false:quota=no
  time created  = Thu Apr 28 20:26:36 2011
  time modified = Thu Apr 28 20:40:38 2011
You can clearly see the "time created" for this file system in the example above.
