How it works

Open a PDF and the current document information (XMP and the classic Info dictionary) is loaded into the fields.
Dates are stored as UTC (standard PDF dates carry no time zone) and are shown and written in that same form, so a value survives a load/save round trip.
You can also strip every field at once, which is handy before publishing a document (this is stronger than the "remove metadata" option in the compressor).
Some producers re-add their own values when the file is opened in another editor; the values you save are what the file contains.
