Yeah, it is "interesting".  I discovered this because I'd floated the
idea of a tiny TimeKit daemon, mainly to deal with setting the system
timezone and emitting signals when it changes.  It's almost like we've
all got the same problem. :)

IIRC, the rationale was that connman is already doing a fair amount of
time manipulation: it has a NTP client and can also (or will, can't
recall) auto-set the timezone based on your geo-IP.  From that it's
just a matter of allowing the user to manually set the timezone.

Personally I'd hope that if a cross-desktop DBus interface was
proposed, that connman would implement it as a wrapper.

http://git.kernel.org/?p=network/connman/connman.git;a=blob;f=src/timezone.c;h=263ee4efe619e7f59a4844477131b09fb0e2cca1;hb=HEAD#l292

It takes the contents of the zoneinfo file and writes it to
/etc/localtime.  It also reads /etc/sysconfig/clock at startup, but
doesn't appear to write that file.  I can't seen where the name is
written though.  This support is pretty new so might have some missing
pieces.  Obviously for more details the connman list is the place to
go.
