How to get the current server timestamp?

Hi everyone,

In PhotonMessageInfo there is:

- timestamp: which I imagine is the current server timestamp;
- SentServerTimestamp: which I believe is the timestamp the server sent stream;

Is there a way to know what was the server timestamp when the PLAYER was writing the stream through PhotonMessageInfo? Or I need to include it in my PhotonStream? If I had to do it, how is the proper way to get the current server timestamp in player code?

I read someone that I need to fetch, but this timestamp could differ from the actual server timestamp from time to time?

Edit: The reason is that I want to know how long has passed since that player started that interaction so I can keep animations up-to-date to everyone in the room.
