Timing diagrams are UML interaction diagrams used to show interactions when a primary purpose of the diagram is to reason about time. Timing diagrams focus on conditions changing within and among lifelines along a linear time axis.
A UML Timing Diagram is a type of diagram used in software and system design to show how objects or components change their state over time. Think of it like a timeline for your system—it helps you see what happens, when it happens, and how long it takes.
What is a timing diagram? Think of a timing diagram as an inverted sequence diagram. In a timing diagram, time passes on the x-axis from left to right, with different components of the system that interact with each other on the y-axis. Timing diagrams show how long each step of a process takes.
However, timing diagrams are made to help you to understand the functionality of a device, so they all want to convey the same message. Let’s look at a more complicated timing diagram, taken from TI’s datasheet for their various synchronous 4-bit counters.

In UML, timing diagrams are a type of interaction diagram that use different notations compared to sequence and collaboration diagrams. They feature a graph or waveform showing the state of a lifeline at a specific moment.
Timing diagrams can be used to document compliance with safety or service regulations where reaction times are important, and to analyse the performance of existing systems.
