Thank you once again Marilynne. I mentioned this task on a railroad forum a year of two ago and some guy thought it was dumb. I disagreed. Most of us who enjoy photography shoot with care and precision. Why wouldn't we also want to take a moment two times a year to be sure our date and time settings are as they should be? Some day our image files will perhaps end up in the hands of a future generation and this kind of thing will matter.
