Hi all,

I wish to calculate the time in another timezone, to acheive this I am using the following structure:

<xsl:sequence select="adjust-time-to-timezone(xs:time('10:00:00-04:00'), xdt:dayTimeDuration('PT4H'))"/>

which returns 18:00:00+04:00.

1. According to http://www.w3.org/TR/xpath-datamodel/ xs:dayTimeDuration is a type defined in the http://www.w3.org/2001/XMLSchema namespace. Why, then, can I only get this to work in the http://www.w3.org/2005/xpath-datatypes namespace when using Saxon 8?

2. Why do I need to declare the datatype atall given that the function is expecting a dayTime Duration datatype, ie why can I just use:

<xsl:sequence select="adjust-time-to-timezone(xs:time('10:00:00-04:00'), PT4H)"/> ?

3. Am I unwise to be using this functionality until these standards become recommendations?
