The 3.30 runtime has empty /usr/share/zoneinfo
The 3.28 runtime has available /usr/share/zoneinfo/ with installed timezones. This is expected.
The 3.30 runtime has available /usr/share/zoneinfo/, /usr/share/zoneinfo-leap/ and /usr/share/zoneinfo-posix/, where only the zoneinfo-leap contains time zones, which effectively breaks timezone lookup by libical.
Is this change intentional?
