Checking on daily minimum temperature script

I wanted to check some details on a download. Am I right in thinking that the ‘time’: ‘00:00’, instance of this script ensure that the 2m temperature since previous post-processing is the last 24 hours even though the CDS web browser offers up 1- 2- and 6-hour options? Am a bit confused. Just want to find the easiest way of downloading daily minimum from 00Z-00Z. Thanks.

c = cdsapi.Client()
