Question: How do you encode simulation/measurement time stamps?

[famura]

Hi there,

I'm currently working on another time series project and need to encode time stamps, e.g. 2023-10-01 12:07:16, as a feature.

A colleague told me that you are used random (Gaussian) Fourier features to encode time. From the appendix A2.1. of your paper I got that you are encoding the diffusion time with this embedding type. Since that time is somehow unit-less, I wonder if and how you encode the measurement/simulation time as a feature?

Best wishes, Fabio
