I think it was around 7am in the UK at that time and later in the day going east across Europe. It was daytime to evening for Asia. I do not think that making sure the US is awake when a coin is launched necessarily makes it any fairer. It was 10:30 in Moscow and 15:30 in Tokyo.
There is a reason why most coins launch at arount 7pm. The launch of HIRO was in the early morning for most of btctalk population. Hardly any Japanese mine crypto due to high power/hardware costs. It can not be denied that you chose a very inconvienient time so dont be offended if people are alleging malintent. I'm not happy with that either but what have been done, was done.
