Returns two timestamps: one with the board time when the module received the IRIG message, and one with the time encoded in the IRIG message.

You can use these two values to determine the delay between the external IRIG source and the module or to test the stability of an external IRIG source against an external time reference.

connector_pane_image
datatype_icon

instrument handle in

The instrument handle that you obtain from Initialize.

datatype_icon

terminal

The terminal that is connected to the external IRIG source.

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

instrument handle out

The instrument handle that you obtain from Initialize.

datatype_icon

IRIG time

The time encoded in the IRIG message.

datatype_icon

timestamp

The board time at which the IRIG message was received.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
