<p>Sure, my workaround will be broken if CLDR project decides just
to swap standard/daylight names but this will also break the main
consumers of CLDR data, namely ICU and OpenJDK (at least current
and past versions of actual software distributions). I cannot
imagine that this is a serious way to go since (what I have
understood until now) your team value backwards compatibility a
lot.<br>
</p>
With best regards and the hope that CLDR data will not simply swap
data in reverse<br>
