Lightroom: Fine Tune Photo time, for multiple cameras in a single catalog.

I often manage a group of photographes at the same event. It would be great if lightroom (and/or bridge) had the ability to adjust photo times to the second and in batchmode, right now it has time zone adjustment and individual photo adjustment.

For example you are sorting photos by time from multiple photographers, and you want to put all the fireworks for instance in actual chronological order regardless of the photographer/camera used. It would be great to choose one photo, have it sync shot time (offset ability, within the sync, would also be also great) with another photo from another camera (or attribute) and select this photo only or entire sequence (from camera or attribute).

It could be an additional metadata attribute, if this helps the programming.

Please adivse if you like this idea, I could really use it by July 26th. Managing 12 photographers at a week long shoot.
