slack-timedate

This program implements timedated1 interface from systemd what is required by GNOME Control Center for now. slack-timedate's purpose is to make it possible to enjoy full GNOME functionality on Slackware Linux which doesn't use systemd as its init-system.

Installation

cmake -B build \
  -DCMAKE_INSTALL_PREFIX=/usr \
  -DCMAKE_INSTALL_SYSCONFDIR=/etc
make -C build
make -C build install

The installation will create a file build/install_manifest.txt, which contains a list of all files installed in the system. To uninstall the application those should be removed, for example by doing:

xargs rm < build/install_manifest.txt

Debugging

Firstly an application is required that changes the time settings over the timedate1 service. It can be gnome-control-center or kcmshell5 kcm_clock for KDE.

Then running dbus-monitor --system as root can be used to see the communication between the control center and this service.

Messages to the D-Bus service can also be sent with dbus-send. For example to get the list of time zones:

dbus-send --system --print-reply --type=method_call \
  --dest=org.freedesktop.timedate1 \
  /org/freedesktop/timedate1 org.freedesktop.timedate1.ListTimezones

To get a value of a property:

dbus-send --system --print-reply \
  --dest=org.freedesktop.timedate1 \
  /org/freedesktop/timedate1 org.freedesktop.DBus.Properties.Get \
  string:org.freedesktop.timedate1 string:NTP
