Setup Fast Clock

JMRI provides two kinds of fast clock capability:

• Internal - the computers clock provides the time information
• External - the DCC system provides the time information

This help page describes the overall structure. There are separate pages for LocoNet clocks and NCE clocks. As yet, we don't have interfaces for clocks in other DCC systems.

There are two different parts to consider: A "Timebase" provides the basic time information, while one or more displays show you what's going on.

To create a timebase, use the "Setup Fast Clock" item in the "Clocks" submenu under the "Tools" menu. This gives you a window where you can:

• Select the timebase source to control (typically, this is the internal computer clock)
• Set the rate at which the clock runs
• Set the time
• Start and stop the clock

Once you have created a timebase by configuring it in that window, you can open clocks that will display on your screen. Currently, JMRI has three types available:

• Analog clock - the traditional circular clock with hands. You can resize it by dragging the window edges. There's also a pause/run button.
• Nixie clock - a digital clock that looks like the old-style Nixie tubes
• Panel clock - you can also embed a clock in a panel (instead of a separate window) from the panel editor.

Happy timekeeping!
