Date functions
Hi!
I am curious what functions I would use with the Ode bpel engine
for some date calculations. In particular I need the following
1. Get the current time of day (hours & minutes)
2. Add/subtract duration to/from the current time of day
3. compare current time of day to another time of day (checking to see
if current time is within a time range actually)
In general if there is some URL pointing to a specification describing
the functions that can be used in xpath expressions within bpel
processes
I would like to have that. I am not sure as to which one I should
refer.
Thanks in advance!
-Doug.

Hi Doug,
There are two versions of Saxon: one commercial (Saxon-SA) and one
open-source (Saxon-B) licensed under the Mozilla Public License 1.0 (MPL).
The open-source version is free (as in beer).
More information at http://saxon.sourceforge.net/
cheers,
alex

Hi!
Alex - Thanks for the references.
I am curious about the licensing impacts of the fact that Ode uses
Saxon.
Saxon appears to have license fees. Are those waived when a commercial
product uses Ode?

Hi Doug,
I would suggest using the XPath 2.0 expression language that supports
many
date-time manipulation functions:
http://www.w3.org/TR/xquery-operators/#durations-dates-times
We use Saxon for the implementation of XPath 2.0, so you can also refer
to
Saxon's own documentation for function details:
http://www.saxonica.com/documentation/functions/intro.html
cheers,

Hi Doug,
I would suggest using the XPath 2.0 expression language that supports many
date-time manipulation functions:
http://www.w3.org/TR/xquery-operators/#durations-dates-times
We use Saxon for the implementation of XPath 2.0, so you can also refer to
Saxon's own documentation for function details:
