With NEM, Nemesis time which represents time 0 can be understood by looking at the program.

	private static TimeOffset timeOffset = new TimeOffset(0);

	static {
		final Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
		calendar.set(Calendar.ERA, GregorianCalendar.AD);

Q1
Which official document that defines Nemesis Time should be referred to?

BTW,

And at the time of the blog NEM launch is listed at the following times.

2015-3-31 19: 00 UTC

Q2
I understand about this time that public release was 31st.
Is this a problem with this recognition?

Thanks.
