Problem
solana epoch-infouses recent performance samples to estimate the epoch's elapsed and total times. However, the samples only cover the last hour. This is a good enough estimate for the remaining epoch time, but we actually know the elapsed epoch time from the block times.Summary of Changes
Use block times for the epoch-start and current Slots to calculate epoch-completed time and refine the total epoch time estimate.
Fixes #17472
