Use TIMESTAMP instead of DATETIME. TIMESTAMP's internal format is UTC; values are converted as you insert/select by adjusting according to the declared timezone. That can be either declared in MySQL or inherited from the system.
Another benefit of TIMESTAMP over DATETIME -- 4 bytes instead of 8.
So -- you did get a 60x speedup with the summary table with 1/60 as many rows? (The 60x was theoretical.)
