Question 

The SIS XSD version 2 has "Z" at the end of the dates, e.g.:

<start_date>2014-10-26Z</start_date>

What’s the ‘Z’ for? 

Answer 

To specify a time zone, the date is indicated in UTC time by adding a "Z" after the date - like this:
<start>2002-09-24Z</start>

or it is possible to specify an offset from the UTC time by adding a positive or negative time behind the date - like this:
<start>2002-09-24-06:00</start>
or
<start>2002-09-24+06:00</start>
