KRPC variable server side timestamps?

[Ender1618]

I am a newbie to KRPC, but I was wondering if there was a mechanism for getting server/game time stamps for the state of a variable, such as the vessel’s velocity vector. Say I registered a stream for velocity, and I query the stream at client time t0 and then slightly later at time t1. Is there a way to know the sever/simulation side elapsed time between the 2 observations?

I would think just having client side t0 and t1 and thus client side elapsed time (delta t) wouldn’t be nearly as accurate. Say for use in a client side PID algorithm, for control of some Kerbal system over KRPC.

Thanks,

Yes, you can query the server for it's time at t1c and then at t2c, the subtract them to get the ∆ts

What part of the kRPC api lets you do this?

So you would query time at t1c, then immediately query the variables you want, then again at t2c?

How would you know that the variables pulled correspond to the the t1s and t2s timestamps, is there a way to batch the calls, to ensure they are from the same server time step?

Thanks,

I don't know specifically about the kRPC API, but I am more speaking in general about what I would recommend doing. 

Querying the values at two different client times will give you the ∆t of the server between the two client times, which can determine if the server is running slower or faster than the client. Batching would _not_ be recommended, because that defeats the purpose of having the ∆t on the client side.
