Hi,

I am not sure what you intend to do exactly, but my bet is that you could do that using an external function. From the documentation:

An external function defines an interface to one or more functions written in the C language (which can be a wrapper function interfacing source code written in, for example, Fortran). Such an external function can be used, for example, to interface a user-created shared library. Note that the extension of a shared library file depends on the platform: .dll (Windows), .so (Linux), or .dylib (macOS).

So you could create a simple C program with no input and which outputs the system time, and then process that in any way you want in your model.

Hope it helps!
