The measured operator execution time is higher than the result in the tuning log file

Hello, everyone.

After auto-tuning for an op, I measure its execution time by .time_evaluator. But the measured execution time is higher than the result value in tuning log.

"result": [[0.00018908600000000004], 0, 3.218310832977295, 1657804190.9171333]

the measured execution time: 0.000349

Why? Which value is the true execution time of the op?
