How to shift timestamps on all photos

Hi  - I'm on Holiday and forgot to change the time zone on my camera.  Is there a way to shift the timestamps on all photos by +/- a fixed number of house?

I looked in Bridge but I only see the ability to do one at a time,

I used a 3rd party software, ExifEditor and it shows the changes on there, but the changes don't reflect in Bridge.

The reason I ask is I like to batch-rename my photos using Bridge to "Sequence Number, Date, Time" so I need Bridge to recognize the correct time.
