How to specify a time range while using a get request for CPU and Memory stats (iControl REST API)

Hi,

I am using the below query for getting CPU and memory stats for an LTM

https://<ip>/mgmt/tm/sys/memory

https://<ip>/mgmt/tm/sys/cpu

When I pass the query, I get a point in time snapshot of the stats.

I want to get data for a specific timeframe. Can someone help on this?

Thanks in advance :)
