Timestamp

R2026b

Output signal timestamp in Run in Kernel mode or Priority mode

• 

Timestamp block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink Desktop Real-Time / Target Profiling

Description

The Timestamp block outputs the timestamp for its input signal. The timestamp is relative to model start time in Run in Kernel mode or Priority mode. The input signal can be any signal of any data type.

In Connected IO mode, this block does not perform any action. It outputs zeros.

Input

Signals — Signals for which to capture timestamps

vector

The actual data values are ignored.

Output

Timestamps — Timestamps of signals

vector of double

For each signal connected to Signals, the block returns the signal timestamp measured from the beginning of model execution.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"sldrtlib/Target Profiling/Timestamp"

Example: add_block("sldrtlib/Target Profiling/Timestamp","myModel/myBlock",MakeNameUnique="on")
