SysV timezones in DT::TZ
Message ID:

I've knocked together an implementation of SysV/POSIX
timezone specifications for DateTime. Code is at
<http://www.fysh.org/~zefram/tmp/SystemV.pm>. This is my first go at
implementing anything in the guts of DT, so experts here please check
that I'm using the interfaces correctly. I don't quite follow what the
semantics are meant to be when a DT object has its timezone changed.
I'm not clear on which DateTime methods a timezone object can rely on,
in the arguments it is given to the _for_datetime methods. I need to
do Gregorian arithmetic even if the DateTime isn't Gregorian. I used
only ->utc_rd_values and ->local_rd_values, and then called out to my
Date::ISO8601 module to do the date arithmetic.
Is it OK for me to put this on CPAN?
