In english? All right, here you go.
1/ Ubuntu 8.04 - Hardy Heron
2/ Clock applet, v. 2.22.2
3/ In the clock applet, section "Emplacements" (= "Locations"?), I added the town of Cayenne. The catch is it is listed in the location database as part of "Guinée française" (= French Guinea).
4/ This piece of information is inaccurate. As a matter of fact, Cayenne is part of "Guyane française" (= French Guyana).
Thanks for your help
PS : as you may have guessed, I'm using the french version of Ubuntu and I have no idea if this error is related to the french translation or comes from the english original version
