But it only defines "summer-time period" for the purposes of the Directive
- i.e. when the period starts and ends - but not for any other purpose. It
does *NOT* name the time periods. So, provided that the dates don't conflict
with the Directive (which they don't), Ireland is free to use the terms
"standard time" and "winter time" if it wants.
