87 # Referendums in the other three countries voted Yes.)

89 # Estonia ... uses EU dates but not at 01:00 GMT, they use midnight GMT.
90 # I don't think they know yet what they will do from 1996 onwards.
91 # ...
92 # There shouldn't be any [current members who are not using EU rules].
93 # A Directive has the force of law, member states are obliged to enact
94 # national law to implement it. The only contentious issue was the
269 # Here is another incorrect claim by Shanks & Pottenger:
270 # * Jersey, Guernsey, and the Isle of Man did not switch from GMT
271 # to daylight saving time until 1921 Apr 3, when they began to
272 # conform with Great Britain.
273 # S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
274 #
275 # The following claim by Shanks & Pottenger is possible though doubtful;
276 # we'll ignore it for now.
277 # * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
278 #
279 #
280 # Whitman says Dublin Mean Time was -0:25:21, which is more precise than
281 # Shanks & Pottenger.
282 # Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
283 # (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
284 # to London. For example:
285 #

85 # Plus, from 1 Jan 81: Greece.

87 # Plus, from 1 Jan 95: Austria, Finland, Sweden. (Norway negotiated terms for
88 # entry but in a referendum on 28 Nov 94 the people voted No by 52.2% to 47.8%
89 # on a turnout of 88.6%. This was almost the same result as Norway's previous
90 # referendum in 1972, they are the only country to have said No twice.
91 # Referendums in the other three countries voted Yes.)
92 # ...
93 # Estonia ... uses EU dates but not at 01:00 GMT, they use midnight GMT.
94 # I don't think they know yet what they will do from 1996 onwards.
95 # ...
96 # There shouldn't be any [current members who are not using EU rules].
97 # A Directive has the force of law, member states are obliged to enact
98 # national law to implement it. The only contentious issue was the
273 # Here is another incorrect claim by Shanks & Pottenger:
274 # * Jersey, Guernsey, and the Isle of Man did not switch from GMT
275 # to daylight saving time until 1921 Apr 3, when they began to
276 # conform with Great Britain.
277 # S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
278 #
279 # The following claim by Shanks & Pottenger is possible though doubtful;
280 # we'll ignore it for now.
281 # * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
282 #
283 #
284 # Whitman says Dublin Mean Time was -0:25:21, which is more precise than
285 # Shanks & Pottenger.
286 # Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
287 # (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
288 # to London. For example:
289 #
290 # "Timeball on the ballast office is down. Dunsink time."
291 # -- James Joyce, Ulysses
292
293 # "Countess Markievicz ... claimed that the [1916] abolition of Dublin Mean Time
294 # was among various actions undertaken by the 'English' government that
295 # would 'put the whole country into the SF (Sinn Féin) camp'. She claimed
296 # Irish 'public feeling (was) outraged by forcing of English time on us'."
297 # -- Parsons M. Dublin lost its time zone - and 25 minutes - after 1916 Rising.
