Re: time difference help

Hi Kent,

Assuming you're using XSLT 2.0 and that the elements are actually
called <due-date> and <actual-arrival>, you can use the minus operator
as follows:

  xs:dateTime(actual-arrival) - xs:dateTime(xs:date(due-date))

to get the xdt:dayTimeDuration P6DT22H21M30S (6 days, 22 hours, 21
minutes, 30 seconds). You can then use the days-from-duration(),
hours-from-duration() etc. functions to extract the values of the
individual components from that duration in order to make something
readable.

Note that the xs:date() constructor constructs an xs:date from the
due date, and the xs:dateTime() constructor casts this to a
xs:dateTime by adding 00:00:00 as the time.

Cheers,
