Here is a brief description of the problem:
"The problem is that timezone updates happen frequently. Therefore
timezones were split out of the glibc package so they can be updated
separately via volatile.debian.org and point release updates. Every
package that ships it's own timezone information needs extra care (which
usually means it gets outdated rather quickly). So the goal is to use
glibc's timezones from the tzdata package (which e.g. python-dateutil
uses) everywhere."
I am not sure how best to handle this problem. The best obvious solution
would be to configure calendarserver to use this timezone database. But,
looking at the code for pycalendar, I really doubt if calendarserver will
be able to parse libc zoneinfo files. The only other option is to
generate the ics files from the zoneinfo database.
Any suggestion on how to handle this problem would be appreciated.
We already have tools in place to parse the Olson data (which is itself the
source of the OS zoneinfo data) and update the server's internal database.
Typically we do that ourselves and include the updated database in our
subversion repository. However, it is possible for that to be done
independently - but we do not have instructions on that at present.
Also, calendar server supports an implementation of the proposed standard
timezone service protocol
(<https://datatracker.ietf.org/doc/draft-douglass-timezone-service/>). The
goal with that is to allow rapid propagation of timezone data changes
between systems. Our server has the ability to be a "primary" or
"secondary" server. The former being an "authoratative" source of timezone
information (in our case derived directly from Olson data). The later is a
server that pulls its data from another timezone service. The goal is to
properly standardize this new protocol and work on getting people to deploy
servers that anyone can use.
