I just saw davyd’s blog about timezone updates. The timezone information generated by vzic converter is not correct for some locations. Perth is one of them. The generated file did not include any information about daylight savings changes. The timezone information updated in evolution has the right information and has been validated against timeanddate.com and exchange server. Please feel free to add comments to the bug if you find any outdated timezone which is not addressed by this patch.
Set to Rise!!
