My student calendar on https://myportal.unitec.ac.nz/ displays my classes 12 hours earlier than they are. I have checked and the timezone on my laptop is definitely set to the correct timezone. I did a search and discovered that this problem could be because I have privacy.resistFingerprinting set to true and therefore my browser is giving the timezone UTC. I checked this via the browser console. I am in New Zealand so my timezone is 12 hours ahead of UTC so hence the 12 hour difference. I am mentioning this here as I didn't want to bother the folks on Bugzilla until I knew for sure that it was a bug. So I'm asking, is this the expected behaviour for users that have privacy.resistFingerprinting set to true? or is this a bug? I am pretty sure that this problem did not exist earlier in the week when I was running Firefox Developer Edition 69.0b3 (64-bit) (Mac OS); I am now running 69.0b4 and this is when the problem seems to have popped up. So I'm just asking if this is what I should expect if wanting to prevent browser fingerprinting? The calendar is only viewable for users that are logged in, unfortunately.
