I'm trying to get my all of my digital photos organized now that I have
sufficient storage space to keep them all on one drive. That's the
necessary prelude to making a complete REAL backup (i.e. one here, one
there - NOT here IYKWIM).
I'm having a problem. When I first got the K10D back in March 2007 I set
the date wrong, or perhaps failed to set the date at all. I didn't get
the correct date set until 02Oct2007, about 6 months after I got the
camera.
If I sequence the images from 2007 by date, the file numbers aren't in
order. If I sequence them by file number the dates don't make sense.
I have certain events that occurred on known dates where I can compare
the camera date in the EXIF to the date I know the event occurred.
Going from the first KNOWN date AND time - the first day of my 2007
Annual Training - the discrepancy is 452 days + 5 hours (+/- 10 minutes).
Adding 452 days + 5 hours to the EXIF date/time gives me the correct
date and time for when I *know* I took the photo (+/- 10 min).
EXIF date = 10Jan2006 03:04 am; KNOWN date = 7Apr2007 approx 08:00 am
But other KNOWN dates give a discrepancy of 454 days (the + 5 hours
seems consistent throughout).
For the most part, calculating dates by adding 454 days + 5 hours works,
but for some days it just does NOT.
The calculated date is the wrong day of the week. The locations are
places I could not have reached on a day that I worked and the
calculated date does not fall on one of my days off. Plus I remember
that I was at that location on one of my days off.
My first calculated date correction won't work unless I use 453 days -
452 days gives a Friday and 454 days gives a Sunday for a subject I know
I must have been on a Saturday (a Farmers Market that was held only on
Saturdays).
The 5 hours doesn't matter; adding it in still gives the wrong day of
the week (Friday) - subtracting it gives a different wrong day of the
week (Thursday) ... still wrong.
Anyone got any ideas?
There's bound to be an explanation in the way computers calculate dates
for why it's doing this, but I can't see what it is.
