Each of the plists is going to have a time stamp,
and they mean different things.
It is so important that you understand what
these time stamps represent.
Info.plist provides information about the device
that's being backed up.
Everything from all those device identifiers, ICCID,
the serial numbers, the SIM card information--
it is going to contain the phone number, the device
name, the iOS version, sync settings, all of these things.
It also has a backup date.
Now, where you have to be careful--
if Apple iTunes was used, so native iTunes,
the real version, this last backup date
is not the very best date for you.
You are going to see where this time stamp--
you could actually be doing a backup, disconnect the iPhone,
and that time stamp will be after that device was
unplugged.
So it's almost as if it caches to the system eventually.
It's obviously going to be within a few seconds
or minutes, but it is not the exact date.
This time stamp will also be time stamped
by commercial tools that do backup extractions.
So if you use UFED and you do an advanced logic
or you create a backup, it will change this time stamp
to when you did that extraction.
So because of this, this is not our very best time stamp
as long as it's Apple iTunes.
