java.lang.Object net.sf.saxon.expr.number.NamedTimeZone
public class NamedTimeZone
This class attempts to identify a timezone name, given the date (including the time zone offset) and the country. The process is heuristic: sometimes there is more than one timezone that matches this information, sometimes there is none, but the class simply does its best. This is in support of the XSLT format-date() function.

date
- the dateTimeValue, including timezonecountry
- the two-letter ISO country code
public static String formatTimeZoneOffset(DateTimeValue timeValue)
timeValue
- the value whose timezone is to be formatted
public static String getOlsenTimeZoneName(DateTimeValue date, String country)
date
- the dateTimeValue, including timezonecountry

public static Boolean inSummerTime(DateTimeValue date, String region)
date
- the date/time in questionregion
- either the two-letter ISO country code, or an Olsen timezone name such as
"America/New_York" or "Europe/Lisbon". If the country code denotes a country spanning several
timezones, such as the US, then one of them is chosen arbitrarily.
