Firefox screenshots are saved with wrong time

Screenshots made from the Developer Tools are saved with the time taken embedded into the file name. On my machine that time is in the time zone UTC+08, where I was a month ago. However, my Windows 10 machine is in time zone UTC-05, where I am now. The correct time is reported when I run in the JavaScript console:

Date()

How is it possible that time zone for the screenshots file names is still wrong? How can I fix that?

I think the time string comes from this code:

Does this also happen with a screenshot via "Take a Screenshot" ?

No, and I gave wrong information. It's not the wrong time zone. It's simply that the day is plus one:

The first one was taken from the Developer Tools, the second one using the popup menu.
