From 2:15 to 3:15, good explanation of whether the values will be picked in the 'reverse' (/earlier than the time) or 'forward' direction. Video also talks about 'nearest' as if, we can ask Pandas to pick the nearest value whether it is in 'reverse' or 'forward' but doesn't show how to get it done. Did I misunderstood you, meaning only either of 'reverse' or 'forward' can be used?
