Hi Addison, hi all,
I made some concrete proposals for XQuery / XSLT users and integrated them
into the Wiki [1]. Please comment them / change them as you like. I added
the following:
Recommendations for XQuery / XSLT
The following recommendations are for users of XQuery / XSLT who have to
deal with time zone sensitive data:
1.
If possible, make sure that your data always contains an explicit
time zone which should be UTC (i.e. computer time).
2.
Do not apply any operations based on date / time types (e.g.
indexing) if you are not sure (a) whether your data has time zone
information at all, or (b) whether the data collection might encompass a
data subset without timezones or might mix computer and wall time.
3.
If you have data like 2, before applying any date / time sensitive
operations, adjust the time zone of the data to UTC with the functions for
time zone adjustment, cf. [WWW]
http://www.w3.org/TR/xpath-functions/#timezone.functions.
4.
If you have data like 2 (b) and you do not want to adjust the data
subset which already has a time zone, make sure that you recognize this
data subset, e.g. via the component extraction functions [WWW]
