lat/lng coordinates in file zone.tab

[Marc Wick]

Hi

Four timezones have coordinates in the zone.tab file that are far away 
from the real place. I have listed the correct lat/lng below. Could 
someone please modify the file?

Africa/Gaborone: correct to -2439+02555
(the current -2545+02555 is in South Africa)

Pacific/Noumea: correct to -2216+16627

Pacific/Tongatapu: correct to -2110-17510

Europe/Vatican: correct to +415408+0122711
(the current +4154+01227 is in Italy)

Thanks.

Best

Marc
