But I can't find the way to get value at
Is there any way to get value at specific time ?

If you are trying to get the value
deltaof two point on certain time. You can try
deltafunc in PromQL.
For instance, if I want
query_count@1609746000 - query_count@1609742400 (P.S. not a PromQL), the time delta is 1hr, so I can do
delta(query_count[1h]@1609746000), it will delta the first and the last value between 1609746000-1h ~ 1609746000
