From DateTime

R2026b

Extract value of DateTime input signal

Since R2026b

• 

From DateTime 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 / DateTime

Description

The From DateTime block extracts the value of a DateTime input signal.

Examples

From DateTime Block

This example shows how the From DateTime block converts a DateTime signal to a numerical signal. The block's input is a signal containing the DateTime value 01-Jan-2000 00:00:00. The block's output is the value 946684800, which is the number of seconds between 01-Jan-2000 00:00:00 and the Unix epoch (01-Jan-1970 00:00:00).

Ports

Input

Port_1 — DateTime signal

scalar

DateTime signal, specified as a scalar.

Output

Port_1 — Value of DateTime signal

scalar

Value of DateTime signal, returned as a scalar.

The data type for the output port is the same as the data type specified by the input signal StorageDataType property. The data type can be any of these:

• 'double' — 64-bit double-precision floating point.

• 'int32' — 32-bit signed integer.

• 'uint32' — 32-bit unsigned integer.

• 'fixdt(0,64,32)' — 64-bit unsigned fixed point with 32 fractional bits.

• 'fixdt(1,64,32)' — 64-bit signed fixed point with 32 fractional bits.

• 'fixdt(0,128,64)' — 128-bit unsigned fixed point with 64 fractional bits.

• 'fixdt(1,128,64)' — 128-bit signed fixed point with 64 fractional bits.

Data Types: double | int32 | uint32 | fixed point
