[Tracker] ... elements/1.1/date question. bug?

[Alexey Fisher <bug-track fisher-privat net>]

Hallo all,

i checking the filedates tracker provide and found some thing i can't
understand. For example:

~$ tracker-info P1070214.MOV | grep date
  'http://purl.org/dc/elements/1.1/date' = '2010-03-04T22:00:00Z'
  'http://purl.org/dc/elements/1.1/date' = '2010-03-05T07:06:06Z'

second is creation time in UTS. what is first date?
More info:

~$ stat P1070214.MOV 
  File: âP1070214.MOVâ

Change: 2010-03-05 09:43:51.000000000 +0200

~$ exiftool P1070214.MOV | grep -i date

As you can see, nothing is telling about 2010-03-04T22:00:00Z
