title: XSLT - get timezone offset from locale
body: <p>Is it possible in XSLT to retrieve the time zone offset for a particular locale? There is a function named in-summer-time which takes in a dateTime and a locale identifier. It returns whether the given date falls under daylight savings or not for that country.</p>
  
  <p>I have a requirement where I need to calculate the offset time for a particular locale. For example, I get the local time at Chile and I need to convert it to local time in UK. I can make use of the function in-summer-time to calculate for the daylight adjustments. But, where can I get the actual offset time for Chile?</p>
  
  <p>P.S.: the function adjust-time-to-timezone does not help since it requires the offset time to be passed into the function(like 2013-05-10T08:10:30-05:00). I do not have the offset time (-05:00) information before hand.</p>
