I apologise in advance to whoever produced the data for Estonia in the 93e data as they may have known it was authoritative, but there is no source given. A relative in Tallinn confirms the accuracy of the data for 1989 onwards and gives the legal authority for it, a regulation of the Government of Estonia, No. 111 of 1989. It is interesting to me that changing their timezone arrangements was one of the first things they did in the process of getting out from under 50 years of Soviet occupation. My source doesn't know if any changes will be made in 1996 and beyond to track the change in EU dates specified in the European 7th directive. Even though the dates are currently the same the Estonians change an hour before the EU, at midnight GMT. Peter Ilieve peter@memex.co.uk
