Exactly. Your browser and the code the websites you visit, use the time set to that specific device. So if you're in EST (Eastern Time Zone) and someone posts at 3am in PST (Pacific Time Zone), when you see that post, it will say 6am. The only snag to that is that some forums use a default offset from Greenwich Mean Time that might be different from the offset of your specific time zone. SO, GMT "starts" pretty much in London and the UK and any location that falls north and south of that zone. EST has a -5 hour offset. If you're in EST and the forum you're viewing has a default offset of -6 hours, whatever you post will display a time an hour earlier from your actual EST time. 99% of the time, that's not an issue, but I've noticed it a few times and I had to go into the setting for my profile and change it.
