We actually did exactly that, me and my friends typed in conversions and came up with different times each. That is why it confused us a lot. We even asked on other forums and majority are confused giving different times.
Meta should really have some sort of countdown on their store page for the release times, as not everyone lives in America that buys their games as well. Steam understands this so well that they have "hours left" on upcoming releases down to the last minute.
But thanks for the answer. Even though the meta forum does not state the exact date and time a reply was posted. Which they really should update as well. Just wanting to help and give suggestions so user experience would be better in the future.
Also the thread topic has the keyword "countdown" so can't be blamed to expect an actual countdown in the post ^_^.
