[Bug]: Realtime time format & delay data calculation

[mxbssn]

Own Analysis

• [X] I cannot find my issue in the documentation

A clear and concise description of what the bug is.

I have noticed that the time format for the Real time is different than the one given for the scheduled one, therefore the integration is unable to provide with the delay between the real-time and the scheduled one...   So the delay calculated always shows 0

Unable to add a screenshot, so here's the data :

This was already the case in 0.5.1 and earlier and tbh I am sure I had a reason for it but no longer sure which :) From a HA basics perspective the UTC version is the one to use but when in cards, it is not always easy to display without lots of additional coding, so it is either BOTH times in UTC with TZ or both without.
