The basic idea is to give one bit of context, and whatever would be
the most useful.  In order of preference, it's:

1)  Last mount directory (if available) and last mount time
2)  Time file system was created
3)  Time file system was written

#2 or #3 is only needed if the file system was never mounted.

#3 is only needed for those file systems that (a) were never mounted,
(b) was modified/filled via e2tools or debugfs.  (Or Windows FS SDK
based hacks, etc.)
