The program enables to set the file time stamp (i.e. date and time) from the EXIF date/time and also enables to shift the time stamp of multiple files.

What is this useful for?

For synchronizing time stamps of files from multiple digital cameras.

Why should I synchronize file time stamps?

O.K., let's start with a story..

Eq-3 mobile phones & portable devices driver download for windows. With a group of our friends we usually rent a big chalet for one week holidays. Last year we have found a beautiful one, in mountains, far away from the nearest village.. this is not important for our story; important is the fact that we had there two digital cameras and made a lot of snaps while enjoying the travels in the nature.

After the holidays I got a task to put images from both digital cameras to a CD and copy it for all friends. So I have put the images from both cameras to single folder, set ascending sorting by date/time in my old-but-still-good ACDSee 3.0 and enjoyed viewing the photos - sorted by time stamp they fitted together wonderfully, like a LEGO.

However, as I have found later, this was only an exceptional case. Next time I had to put together snaps from a wedding; that time I got CDs with snaps from four cameras. But unfortunately simple sorting by time stamp did not work this time. Why?

1. On one camera, the software which was automatically rotating portrait oriented snaps during the transfer, assigned to these snaps the time of the transfer (made in the evening).
2. On another camera the internal clock was set inaccurately - it was about 15 minutes late, so the snap of the first matrimonial kiss was sorted between photos from other cameras made on the way out of the town hall.
3. On the third camera the time was (almost) correct, but without a respect to the daylight saving adjustment, so it was actually shifted by one hour.
4. And besides this, one of the guys used some graphical editor to enhance some of the photos - and this destroyed both the EXIF information in the JPEG files, as well as the file time stamp.

As a result, I had to change the time stamp on more than 3/4 of all the photos, the number of which was over 700! After unsuccessful looking for some software which would help me with this task I have decided to write my own. Here it is.

The program is pretty simple. It enables to get the time from the EXIF info (stored inside by the JPEG file) and set it as the time of the file. This is useful for fixing the case (1).

It also enables to select multiple files in a list and shift their date/time by a time slice - by single click you can increase/decrease seconds, minutes, hours, days, months or years. This is useful tool for cases (2) and (3).

Unfortunately for the case (4) there is no other solution, than to estimate somehow, when the snap was actually made and then set this time manually. This program at least makes this task more comfortable.

How to use the program

Before merging the snaps from different cameras into a single folder, it is better to leave them for the moment in separate folders, i.e. snaps from each camera in its own folder.

Fixing the case (1)

• Select the folder by the 'Select folder' button and sort the files by file date/time by clicking in the header of the Original time column.
• Investigate the files at the end - usually the wrong date/time is later than the correct one.
• If you find such files there, select them and press the 'Set time from EXIF' button.
• If the files contain EXIF information in proper format, you will see new date/time appearing in the right column. If not, then the files belong to the case (4).
• It is not a mistake to select all the files and set the date/time from EXIF for all of them - if the date/time of the file is correct, resetting it from EXIF should not harm it.
• Press the 'Apply' button to set the new date/time to the files on disk; the Apply button is used for all files, not only for the selected.

Fixing the cases (2) and (3)

These two cases are identical in principle - you need to shift the time by the same time slice on all the selected images.

On some types of events it is necessary to synchronize the images with a one-second precision. The wedding was a typical example; the first matrimonial kiss of the engaged couple was pretty short event (few seconds), but fortunately was also the event everybody was shooting, so such snaps then served very well as reference snaps.

• Select the folder with snaps from the camera, about which you are persuaded it had the correct time.
• Find the snap of the kiss and set it as the Reference image 1 (press the button). Setting it does not perform any action; it only displays this file date/time stamp permanently in the toolbar so you are now free to select another folder with images from another camera.
• In the next folder find again the snap of the kiss. Set it as Reference image2.
• Now you can select all the images from this camera and start modifying the time. Click on the time modifying buttons (with arrows) so that the reference snap 2 will get the same time as the reference snap 1. All the selected images will be shifted by the same amount of time, so this action will synchronize the images with the first camera.
• When you are done, press the 'Apply' button and continue with the folder from another camera.

Fixing the case (4)

If the image contains no information about its time, neither in its file time stamp, nor in the internal EXIF info, then you must guess its date/time. The most comfortable way how to do so it the following: Drivers hatch.

• Merge the files from various camera to single folder before proceeding.
• Run the program twice, so that you get two windows.
• In one window select the file with the wrong time.
• In the other window sort files by time and look for the place where the snap would fit. When you find the place, you can estimate the date/time needed to be set.
• Return to the first window and set this date/time on the file. Press the 'Apply' button.
• Switch to the second window, and press the 'Select folder' button. Select the same folder (i.e. do not change the folder) and press OK. This forces re-reading the information from disk. Now you can check if the file is placed on the proper position (files need to be sorted by original time).
• Repeat the same process with other files.

With the timestamp method you can change the date and time of the filename. Hokuyo automatic port devices driver download for windows. You can either change it to a fixed date/time, a date/time relative to the current date/time of the file, date/time from EXIF tags in images, or a pattern in the filename.

Apply to
A file contains three different date/time values. One for when the file was originally created, one for when it was last access, and one for when it was last modified. Use these checkboxes to select which date/time values you want to change. You can check more than one of them, but at least one has to be selected.

Image date and time
If this is checked and the files in the list are image files the date and time value will be set to the EXIF date taken value found inside the image file.

Absolute date and time / Delte date and time
This determines if the values of the edit fields below are the absolute time or if the values are relative to the files current date and time.
Note: When you change from absolute to delta time, you should review the values of the edit fields.

Filename pattern / Dirname pattern
When checked a pattern edit field will be visible in the bottom. In this field a pattern for how the date and time values can be retrieved from the file or parent directory name. The tags <Year>, <Month>, <Day>, <Hour>, <Min>, and <Sec> have special meaning in this method. They are used to specify how the date and time parts are recognized in the name.

Example: If you have a filename with year, month, and day values in the name and you want to set the file date to this date and the filename is 'Summer at the lake 2011-04-01.jpg' the pattern <Year>-<Month>-<Day> will automatically retrieve the date.

Regular tags can also be used in the pattern, but note that the six date and time tags have special meaning here.

Day / Month / Year / Hour / Min / Sec
When absolute or relative date/time is checked you can specify individual time parts in these six fields. If Delta Date and Time is checked, these values are either added to or subtracted from the file date/time. If you type 1 in Hour, 1 hour is added to the date/time and if you type -1, 1 hour is subtracted from the date/time.
