Dates for documents are off by 1

If for instance you go to this page:

https://www.pwg.org/standards.html

and you look at the date for a document, the system uses the publication date of the document (I'm guessing the date code from the file name) to present the date on the web page. The form to create a listing doesn't have a field to manually set the date.

What is wrong is that the page presents for each document the date for 1 day before the document publication date. For example, IPP 3D Printing Extensions is cs-ipp3d10-20170210-5100.21.pdf, so was published on 2017-02-10, but the site lists its date as "Feb. 9, 2017".

I noticed that this morning; it's a timezone thing... :/
