Say, if I created a waitable timer using CreateWaitableTimer API and then set it using SetWaitableTimer. Can I find out when that timer will fire only by the HANDLE returned by the first API?

No you can’t.
But there is nothing preventing you from creating a wrapper object that will publish a similar API, record the target time (by adding the due time to the current time when
SetWaitableTimeris called), and provide the outstanding time to you as a difference between the current time when the query method is called, and the target time.
