Potentially very stupid question:

How do I go about adding/subtracting etc. the values of two XML elements via
XSL?

For example, I have the following:

	<Publication>
		<PubDate>07 May 2001</PubDate>
		<PubTime>10:08 PM</PubTime>
		<PubOffset>-5</PubOffset>
	</Publication>

I'd like to be able to take the PubTime and PubOffset to display the time in
PubTime, GMT or local time of the viewer.  So, using the above values, I'd
like to be able to convert the time to GMT based on the offset, which in
this case would be 2:08 AM.

Many thanks,

- rich
