@gargoyle99 upload time displayed is not subjective to the user time zone, server time is always Central European Time, which is currently GMT +1, as frosty confirmed above if you are in the UK during winter time the site time will be 1 hour ahead. During summer UK switches to BST (UTC+1) and CET switches to UTC+2. So it's actually 1 time ahead all year long.
tl;dr: site time is always CET, how behind/ahead you will be depends on your time zone.
