Hi all, Is there a way in MC20 latest to adjust the time a bunch of pictures was taken. I need to adjust them by minus 4 1/2 hours.
Can I do it with multiple photo's at the same time?

i.e an exif time of '2015-01-25 21.30' becomes '2015-01-25 16:30'

Can MC do this?

You edit the date field in the Tag Action Window and enter an expression like:
=[Date]+60

That would make it one hour later.

I think the updated date / time get written to the EXIF tags.

Try a few before you do them all.  Ctrl+Z undoes any changes.

There may be another number bug kicking around in there somewhere as for me, =[Date]+60 actually kicks it back an hour, not forward.

MC steadfastly refuses to write EXIF data... http://yabb.jriver.com/interact/index.php?topic=92156.msg634233#msg634233

We write the new date to the IPTC / XMP tag, but leave the EXIF tag alone.

This omission is the only reason I still have AcdSee installed here.

Re. Number bug...
Matt said:

You need to call it out with Math(...):
=Math([Date,0]+10)

The number added is the number of days.  Add a fraction for time, like 1/24 for an hour.

If it's not called out in Math(...) some mystery happens.

Thanks Marko, but if it does not update the EXIF tag then.....
