The main rationale for adding it was to avoid having gnome-shell mmap'ing /etc/localtime once a second. However, we can just as easily run inotify there, and given no one else was clamoring for a way to detect when the time zone changes, I don't see a need for public API here - at least not yet. In the bigger picture, I just don't believe that the vast majority of applications are going to go out of their way to instantiate and keep around a random GTimeZoneMonitor class. And if they do, it's has the side effect that for other bits of code in the process, local GDateTime instances may start varying again! So, if code can't rely on local GDateTime instances being in a consistent state anyways, let's just do that always. The documentation now says that this is the case. Applications have always been able to work in a consistent local time zone by instantiating a zone and then using it for GDateTime constructors. We fix the "gnome-shell stats /etc/localtime once a second" issue by using timerfd (in glib) and inotify (in gnome-shell). https://bugzilla.gnome.org/show_bug.cgi?id=655129 |

This package contains the reference documentation for GLib. For more information about Glib, see: http://www.gtk.org For information about contributing to the GLib/GTK+ reference documentation project, see: http://www.gtk.org/rdp/ The GLib reference documentation is freely redistributable, see the file COPYING for details. REQUIREMENTS ============ To build the documentation, you must have the gtk-doc package installed. To rebuild the template files, you must have the current version of the GLib header files installed. BUILD ===== First, run configure to generate the makefiles for this module. There is one option specific to this package --with-html-dir=DIR top of installed HTML documentation tree The Makefiles for this module define three targets: templates: Scan the headers and merge the results with the current template files sgml: Generate SGML files using the DocBook DTD from the template files html: Generate HTML from the SGML files. To build the documentation, do: make sgml make html You should only run the 'make templates' step if you need to regenerate the templates for a more recent version of the GLib sources. INSTALLATION ============ make install
