I need to display a label with the current time zone abbreviation. My pc\'s timezone is currently set to \"(GMT) Greenwich Mean Time : Dublin, Edinburgh, Lisbon, London\".
I think you have two choices: Special case handling for the GMT time zone, or generalized handling for "Time zones for which Microsoft uses an incorrect name."
I wonder, for example, whether the Portuguese use "GMT" for their time zone in the winter. Whether they do or not, I doubt they use "British Summer Time" in the summer!
