With PMB, you can change the date/time of multiple media files in a batch.

The screen design may be different depending on the version of your PMB.

In Calendar View or Index View, select the media files you want to change the date/time. You can select multiple media files at the same time. The selected media files are marked with a blue frame. Refer to <this page> for details.

Select [Edit] > [Batch Date Change...] in the menu.

The [Batch Date Change] window opens. Change the date/time and click [OK].

There are 2 options for how to change the date/time. ［Change dates of all media files to keep their time the same, relative to the selected media file］ Select this to manually adjust the date/time of one of the selected media files. According to this adjustment, the date/time of other media files will be automatically shifted to maintain the same time interval. ［Change date by specifying a time interval］ Select this to specify how many hours, minutes, or seconds should be advanced or returned from the original date/time of the selected media files.
