There are certain times when you might want to change the capture time for an image. For example you change time zones when traveling and forget to reset the time on the camera, or maybe multiple cameras are used to photographed an event, only one camera was incorrectly set (making the Sort by Capture Time difficult as the images appear out of order due to the incorrect time stamp on that camera’s images). In order to correct the time, select the images from that camera (don’t forget you can easily filter on the metadata/serial number of the camera to quickly find all of the images), and choose Metadata > Edit Capture Time. Choose to adjust to a specific time (for example, if the time needs to be set 8 minutes forward) enter the correct time and all of the images will be shifted appropriately. If you changed time zones, then choose to Shift by a Set Number of Hours.
In addition, there is a preference that goes along with it that many photographers aren’t aware of. If you choose Catalog Settings > Metadata you can choose to Write date or time changes into proprietary raw files. This is the only occasion when Lightroom will actually write changes to the proprietary file (.nef or .crw for example).
