Until now, I haven't found a Mac tool that enabled me to batch correct the capture date/time for when I forget to reset the camera clock to the correct time zone. On Windows, I always used Breeze Browser to correct the date/time, but this feature was lacking on every Mac photo tool that I had tried.
Of course, I forgot to reset the clock on my cameras since my return from Tanzania. I finally realized that the clock was wrong when I was reviewing some of my firework shots, and noticed the July 5th date. It looked like that I was going to have to dig out a Windows PC from the garage to correct my exposure date/time. Before heading to the garage, I took one final look on my Mac tools to see if anyone had added this functionality.
To my delight, Photo Mechanic now offers a method to adjust the capture date/time metadata -- this feature was not available in October when I last looked for it.
If you know your camera clock was off by some time delta (e.g. 3 hours since you changed 3 time zones), simply dial in the delta time in the Adjust Relative section.
To precisely adjust the capture times, use the Adjust Absolute controls to set the absolute time a photo was taken.
The only problem is that the Photo Mechanic software is not smart enough to realize when the date needs to be adjusted if a relative time adjustment crosses the midnight mark. For example, if I took a photo at 10PM on July 4th, but later realized that my camera was still set to EST time zone, the camera recorded the capture date/time as July 5th, 1am. Doing a -3h Adjust Relative operation should automatically cause the capture date to change to July 4th.
Breeze Browser does this perfectly on Windows, but Photo Mechanic leaves the capture data unchanged.
Oh well, I can at least manually force a new capture date now.
