Hi, all I found that there is a 'new' dir /usr/share/zoneinfo-leaps It includes files almost the same ones in /usr/share/zoneinfo/right/ I checked the md5 of every files under those two dir. And found that they are the same ones. The only exception is /usr/share/zoneinfo/right/US/Pacific-New, which has no counterpart under zoneinfo-leaps. ls cmd told me that Pacific-New is a hard link to Pacific, Los_Angeles.
