Rolling window limits?

Hi!
Does the library support rolling windows limits?
For example, if my limit is 60 per hour, there are 2 ways to go about it
1) If the user hits the limit, she has to wait for 1 hour before the limit resets. Making even one call during the one hour time period will extend the limit by another hour. For example: if I made 60 calls in 1 hour, and then make one call in 1:59, I will be rate limited, and will have to wait for until 2:59 for the limit it reset )
2) The limits get incremented as the time window slides, to always count only the events in the last hour. For example: if I made 60 calls in 1 hour (5 of which were in the first minute), and 1:01 I am allowed to make 5 more calls.

Based on reading the code, I think only 1 is supported, but just want to make sure
