Time & Date

I have recently taken two consecutively numbered images of the same subject. However, when I viewed the details one image is timed at 06.56 and the other at 08.20. As I did not wander away and back again or, as far as I know fiddle with the clock, how can this be? All the subsequent images were timed after 8.20. Any assistance would be appreciated.

Where are you looking at this? In the camera? In an editor later?

The Nikon Exif has three "times" in it... Creation, Access, and Modified.

If you put it into the computer, software can then modify some of those times.

My only point is that you should verify you are looking at "Creation" time.

I am looking at the images side-by-side on the comp and hovering the mouse over the image shows the time & date taken.

Has the camera been set aside with no battery for any length of time? It may be that the small internal battery to keep the clock and settings is low on charge?

OK, then you are wrestling with Windows instead, not with the camera Exif.

Windows Explorer can choose to show different things. In this folder (where you see this), select menu View - Choose Details (I am speaking Win7).
In that box, there is Date at top, BUT scroll down to the several Date entries (alphabetical). There are MANY date choices it can display.
You may prefer Date Created, or Date Taken.

Or, maybe look at it someplace else than Windows... Properties in a photo editor maybe.

No it is not Windows. It is a simple matter of something having happened between taking the two images. I am comparing like with like. All the early images were timed up to 06.56 and all the subsequent images were timed 08.20 and after. The camera has always had a battery in whilst being stored. As far as I know I did not tamper with anything in the interim.

1) does it really matter much?
2) if so why not upload both images with full exif supplied so people actually have something to work from rather than just playing a silly guessing game

Well, then, it sounds like maybe your camera clock time got changed somehow, accidentally. That's about an hour, maybe time zone or daylight saving time? That Time and Date menu is in the camera Setup menu, I'd check it to make sure it was set right now. If it is about an hour fast now, accidental change might be an explanation.

I'm betting that's the ticket. Daylight Savings Time will try to auto-adjust the time by jumping forward an hour in the Spring, or back an hour in the Fall.

The camera won't automatically change the time for DST, when the clocks change you have to manually set the setting for DST being in effect.... I guess it's because cameras travel and it doesn't always know what time zone you are in.

Actually, it will. Not sure about the D7000, but in the D7100 manual it says this about Daylight Saving Time - "Turn daylight saving time on or off. The camera clock will automatically be advanced or set back one hour. The default setting is off."

edit: Just pulled the D7000 manual online, and it says the same thing.

I got confused by that too - When you set it, it advances the time.... But when the clocks then go back in Autumn, it doesn't knock the hour off you have to unset the option again.
It is simply a quick way for you to update the time by one hour, nothing more and it is not automated.... I tried it, my clock was wrong for days while I checked my regional settings etc.

Hrrrmmm... now I've gotta go back and check and see, just for my own curiosity. So used to everything else with that option doing things automatically...

I know, I was the same - With my D3100, and the D7100. In spring you set it, then in Autumn you unset it - Honestly you may as well just change the clock yourself!
I suppose it's for places like the UK where I live... We have DST, so I set it... But if I travel to France, they don't use it, so the time difference varies depending on the time of year.

No it does not matter very much but I am naturally curious.
I am sorry if you think I am being silly to ask such a question but please do not waste any more of your time on it.
I will try to upload the relevant images if anyone else is interested. Many thanks.

Thank you Pretzel and SteveH. I think you have it. When I left the UK for the trip I thought the time was correct and DST turned on. When I returned from Nepal the time was an hour slow and DST turned off. Nepal is 4.30 hrs ahead of GMT. I did not know the time does not change back automatically. As you say SteveH we might just as well keep it switched off and just change the time accordingly. Many thanks for your constructive comments.

Hey that's great news, glad we got the answer for you! That DST setting really needs to be re-written in the manual... When Nikon say it changes the clock automatically, they just mean that one time when you change the setting.

ETA - It wasn't a silly question at all, I spent ages wondering why my photos started coming out with the wrong time, and I hadn't even travelled abroad - I didn't notice for a few months after the clocks went back, so I didn't associate it with DST changing.

In the exif data, you have one parameter which tells you what time zone you have set and of course if daylight saving is on or off. From this you can get the GMT time of each shot. Just check the times; converted to GMT; and see if the gap between shots is what you think it should be.

This is a screen shot of View NX. The data in File Info 2 is what I am referring to.

Many thanks Aroy I will check and try to post the data on here. I travelled to New Delhi about a week after the images were taken in Kathmandu!
